convulsions

Interesting discovery.  I have been in a flare for quite some time now. I had a days relief on Friday and back to the flare.  I have always said my body twitches for lack of a better word. I have found that it is really bad after I am active i.e. walking or wheeling myself in my wheelchair.  Last night, my muscles in my arms and shoulders cramped up so bad I was in tears. I figured I overworked them because yesterday was a wheelchair day.  However, the pain was not tired muscles, it was cramped up painful muscles.  I took some excedrin hoping for some relief. I also had my husband rub some ben gay on them.  I went to bed and turned on the electric mattress pad that generates heat...hoping that it would loosen the muscles up.  I began convulsing after about 45 minutes.  This is not a twitch, it is convulsion.  I could not control it and it would not stop.  I moved off of the heated mattress pad and threw off the blankets.  I did not feel hot but my husband said my body was very hot.  After a few more minutes, the convulsions stopped. I had cooled down.  So, now I know that if I raise my body temp the convulsions are brought on.  I am glad to know this but I am also frustrated and tired of having to go thru all of these things. The docs don't seem to care.  
I googled convulsions because I wasn't sure if that was what I should call my twitching.  Turns out that is exactly what my twitching is and it tied them to epilepsy and MS.  In MS it is paroxysmal disorder....idk...something like that. Will google again and write it in my journal for my neuro. I see her again on Wednesday.
