I can relate. I often get shivering feeling and have goosebumps - even when I am hot. It is possibly related to temperature regulation problems with autonomic peripheral neuropathy. I found this wonderful article recently which I can't find this evening but if I find it, I will post it. Found it but I see that I cannot post links yet. Just Google - Mystery Disease Unraveled by Stanford neurologist.

This article is discussing autonomic dysfunction - which can occur in peripheral neuropathy.

YOu can get shivering goose bump, as a normal response to being startled, or suddenly suprised.
except its part of the neuropathy, mines only lasted for about 2 weeks, but thats when everything started, i also developed RLS(restleg syndrome when trying to sleep, my feet and hands were jerking uncontrollably(not twitching). I still suspect it was related to mixture of diphenhydramine and dxm, that caused long lasting effects. im pretty sure people would be able to feel low-grade fever, you would feel warmer than usual, an malaise. but mines was out of the blue and random.
