Hi. My hands are burning, swelling, and turning red whenever heat is around; whether it be the cat being held, computer heat, sun, water, etc. Nothing makes it go away, I have to wait it out, about 40 minutes or so. Lotion and ice or cool water do not help, they tend to make it worse. For example: you don't put a 3rd degree burned person in really cold water because they'll go into shock.
I have been tested already for thyroid, arthritis, nerve damage and all these came back normal. It's only my hands. It's like a bad heat intolerance. I'm about to make an appointment with regular doctor to see what to do next...possibly an allergy test...it's been going on since around January and recently gotten worse in the last month. I am on a few meds but I doubt those are causing it because I've been on them for a while and we think something would have shown up by now. Sometimes the fingers tingle too, along with the heat.
I personally think it could be MS as I have 90% of symptoms, but of course they have to rule out everything else first. My neurologist who did the nerve test said I had "brisk reflexes" which could be a sign of something wrong with my central nervous system, or nothing at all, some people are allowed to have brisk reflexes.
