Doctors' seeming nonchalance may come from their lack of understanding of the brain. Indeed, science knows very little about the brain. Even if docs know what is wrong, what part of the brain is malfunctioning, often there is no cure or treatments. Doctors are probably at a loss as to what to tell you. Certainly, this has been my experience. Any odd/strange symptom was blamed on the brain injury, the end of story.

I have had pains similar to yours for just over a year. I am progressing, but still have constant pain and strange sensations (it's like a pain orchestra up there. add constant ringing in the ears and it's a full house) My brain has adverse reactions (pain, fever) to vitamins and supplements, so I completely understand that medications can produce even stranger effects.

Hang in there.
