    I operated on DKM in February 2020. When he sat across from me again this July \u2014 over six years later \u2014 I noticed something I see in most operated patients. Confidence in body movements, knowing that a pain attack is not around the corner.<\/p>

    His face was calm. It had always been calm. Even back when he was describing his pain to me for the first time, before surgery. What has changed is everything underneath that calm. Before surgery, that stillness was braced. Waiting for pain to come any moment. A person living with Trigeminal Neuralgia learns to carry a kind of low-grade anticipation everywhere \u2014 will the fan turn on, will someone brush past my face, will I need to brush my teeth soon. Will the pain come when I chew or open my mouth? What if I have to talk?<\/p>

    That tension doesn’t always show up in what a patient says. It shows up in how they hold themselves. This July, that tension simply wasn’t there. He sat the way a person sits when their body has genuinely stopped expecting pain. I’ve learned to watch for that shift over the years, and it’s one of the more honest signs of a good outcome \u2014 more honest, sometimes, than what patients say out loud.<\/p>

    He’s been back to see me twice since his surgery. Not for follow-up in the clinical sense \u2014 just to say hello. Both times, he’s asked to sit in on my OPD for a while and talk to patients who are currently living with Trigeminal Neuralgia, sharing what it was like for him, before and after. He offers to do this as his social responsibility of spreading awareness and supporting diagnosed patients.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    How Acromegaly Hides in Plain Sight<\/h2>\t\t\t\t

    Acromegaly is a disease of slowness. It is caused, in almost every case, by a small benign tumour of the pituitary gland that pours out too much growth hormone. The hormone does its work by fractions. A millimetre here. A half-size there. The face you meet each morning is never very different from the face you met the morning before, and so the change escapes you. By the time it announces itself, it has usually been at work for years. Across large studies, the gap between the first sign of acromegaly and the diagnosis runs to seven, eight, sometimes ten years.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Diagnosing Trigeminal Neuralgia: A Patient Who Noticed What Doctors Missed<\/h2>\t\t\t\t

    DKM is a professor of mathematics at a prestigious university in North India. I think that detail matters, because of how precisely he arrived at his own diagnosis \u2014 well before any doctor was willing to commit to it.<\/em><\/p>\n\n\n\t\t\t\t<\/div>\n\t\t\t<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

    He arrived, having filtered it correctly.<\/em><\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

    It began with a strange, brief electric flash across his forehead while drying himself with a towel after a bath. Most people would let a sensation like that pass. He noticed it, dismissed it once, and then paid close attention when it happened again in exactly the same way, doing exactly the same thing. Most doctors who are otherwise familiar with this disease may tend to overlook an occasional, brief, electric-shock-like pain \u2014 because it’s occasional, because it passes quickly, because on its own it doesn’t look alarming. What an intelligent, observant patient notices, and what a medical consultation may often miss, is that this pain is different in character from ordinary pain, and that it’s unusual precisely because it follows specific, repeatable triggers. A towel on the forehead. Cold water. A breeze. That pattern is the disease announcing itself, long before it becomes impossible to ignore.<\/p>

    DKM saw three doctors before anyone would use the words Trigeminal Neuralgia. He’d already found the term himself by then, matched his own symptoms against the clinical description, and was, in effect, waiting for a doctor to catch up to a conclusion he’d already reasoned his way to. That’s not something I see often. Most patients arrive overwhelmed by conflicting information. He arrived, having filtered it correctly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Living With Trigeminal Neuralgia: Four Years Before Surgery<\/h2>\t\t\t\t

    The four years between his first symptom and his surgery tell you more about this disease than any textbook does.<\/em><\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

    Like standing beside someone welding \u2014 except the electrode was inside his own head.<\/em><\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

    He kept teaching through all of it. In his city, winters are harsh \u2014 temperatures can fall to two or three degrees Celsius \u2014 and cold is one of the more reliable triggers for this kind of pain, which is why winter tends to be the hardest season for almost every Trigeminal Neuralgia patient I treat, not just him. He wore two caps and wrapped a wool band across his forehead to get through those months. He bathed every day knowing, with total certainty, that the moment water touched his forehead, the pain was coming. He did it anyway, because there wasn’t another option. His oxcarbazepine daily dose climbed from 200mg to 1,200mg over the course of a year as the disease progressed, controlling the pain somewhat, but leaving him with a constant dull heaviness that never fully lifted.<\/p>

    He described the pain itself in a way that still gives me goosebumps: like standing beside someone welding \u2014 the electrode sparking against metal \u2014 except the electrode was inside his own head. Three to five seconds of it, he told me, but so intense that anything longer would be unsurvivable.<\/p><\/section>

    My training in neurosurgery, and MVD surgery<\/a>, taught me the pathophysiology of Trigeminal Neuralgia \u2014 the symptoms, the vascular compression, the pain pathways, the mechanism behind why decompression works. It didn’t give me the felt experience of it. That only comes from patients, and only from the ones who can put it into words.<\/p>\n

    DKM’s welding analogy is one I still reach for, years later, when I’m explaining this disease to a newly diagnosed patient, or to a relative who cannot comprehend how the pain can be so unbearable. No textbook gave me that image. He did. He isn’t the only patient who’s taught me something this way \u2014 over the years, a handful of people, usually natural observers of themselves for one reason or another, have described this pain precisely enough that I’ve genuinely learned from them. Not the diagnosis, nor the treatment. But the texture of the thing itself \u2014 how a ten-second event can come to dominate a person’s entire relationship with their own face, their own morning routine, their own sense of safety in the most ordinary moments.<\/p>\n

    A mathematician’s mind, trained to observe precisely and report exactly what it observes, turns out to be unusually well suited to this. DKM didn’t just tell me he was in pain. He told me what kind, how it began, how it traveled, how long it lasted, and how its total absence for twenty-two strange months in 2018 and 2019 felt different from its presence before and after. That kind of self-observation is rare. Dedicating my career to the surgical treatment of Trigeminal Neuralgia and Hemifacial Spasm has made me a better listener with every patient \u2014 including the ones who struggle to find any words at all for what they’re feeling. I ask better questions now, because I know what a complete answer can sound like.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    By the time DKM came to me, he’d already done more independent research into Microvascular Decompression than most referring physicians ever do. He’d read the surgical literature, watched procedure footage from our MVD centre in Pune and centres abroad, and understood the alternative treatments well enough to explain to me, unprompted, why he’d ruled them out \u2014 the other surgical options for Trigeminal Neuralgia carry a meaningful chance of the pain returning within a few months to a year or two, while MVD offered something closer to a lasting answer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    What I remember most, though, is how he framed the decision. He didn’t ask me whether surgery was safe. He understood, correctly, that no surgery is without risk. He asked me to help him weigh which side carried more risk \u2014 operating, or continuing the life he was already living. He put it in terms of probability, the way you’d expect a mathematician to. He concluded that the risk of something going wrong in surgery was small, and the near-certainty of his quality of life continuing to erode without it was the far larger risk. Once he’d reasoned it through that way, he told me, the fear simply left. Not even on the operating table did it return.<\/p>

    I’ve had this conversation, in some form, with hundreds of patients. I don’t think I’ve had it with anyone who arrived at it quite this rationally.<\/p>

    The surgery itself is called Microvascular Decompression. Under the microscope, the cause becomes visible almost immediately \u2014 an artery, pulsing, resting directly against the trigeminal nerve. Every heartbeat, that pulse strikes the nerve. Over years, that repeated contact is what generates the pain. We lift the artery away from the nerve. We keep it separated with a small piece of teflon, placed between the two so the artery can no longer touch the nerve. The compression is gone. There is nothing more dramatic to it than that \u2014 an artery moved a few millimetres, and held there.<\/p>

    He woke up. The first thing he checked for was the pain. It wasn’t there. It still isn’t.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    What stays with me isn’t the clinical outcome on its own \u2014 I expect a good outcome from a well-selected MVD case, and his was one. It’s watching a person who spent four years building his entire day around avoiding triggers now sit in front of me with no tension left in his body. And it’s the fact that, twice now, he’s chosen to spend part of a visit to Pune sitting in my OPD, talking with patients who are exactly where he once was \u2014 not because I asked him to, but because he wanted to. He’s spoken about all this on camera too, in his own words, for anyone who would rather hear it from him directly than read it from me \u2014 his full interview is on our YouTube channel, linked at the end of this piece.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Trigeminal Neuralgia is still poorly recognised, even within medicine. DKM saw three doctors before one would say the words out loud. If a research-minded mathematician, capable of diagnosing himself with real precision, still spent years being told he didn’t have what he clearly had, it’s worth asking how many people without his persistence are living with this pain right now, unnamed.<\/p>

    If any part of what he described sounds familiar \u2014 a flash of current, brought on by touch, cold, or a breeze, lasting only seconds but unbearable while it lasts \u2014 it has a name. Trigeminal Neuralgia.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
