pain was the first harbinger for me of any serious medical problems - thermal allodynia emerged days after I returned to school having been off with glandular fever at age 13.
Ive had it for the 20 years since - when my skin warms quickly from either sun warmth when popping outside or me doing anything exertion wise that warms me up (jogging,picking up a heavy box etc) I get pain randomly dispersed from my waist up to my scalp. it feels like hundreds of very tiny hooks pricking then lifting a little on the surface of my skin, not to be confused with "pins and needles" as this is not an analogy,actually feels like tiny implements.
occurred the first time hopping into an un airconditioned car on a summers day.
I dropped out of some long term forms of exercise in my late teens because people were noticing and laughing at my coping mechanisms like scratching,pressing or light slaps/taps on the affected skin.
something as small as being embarrassed can flush my face with enough warmth for the prickling to make me want to scratch.
in 2009 I got a rarer (I only get it say,once a month as opposed to several times a day with the thermal allodynia)
sensation, after a night of disturbed sleep the skin on my hands and again,everything else above the waist would be affected but they would go almost completely numb in response to anything coolish in temperature Id put my skin in contact with, not at all painful but very distracting and disconcerting when trying to do any task .
does anyone have similar symptoms ?
I got CFS about 13 years after the glandular, a mystery virus that Id guess might have been herpes family cause later on shingles and then cytomegalovirus each doubled the severity of my symptoms permanently (at least so far)
EDIT - thought Id add, in the late 90's I saw a neurologist about the thermal allodynia, he was mystified, tried me on carbamazapine/tegretol then said it was probably something to do with myelin but he couldnt help. saw another neuro in 2012 who said similar stuff, did conductivity tests and an MRI and tried to send me off saying there was nothing wrong at all but admitted he had no way to rule out small fibre neuropathy when I asked if it could be that in the form of post herpetic neuralgia .
