am 22 years old,for two years now i have had a strange sensation on my right side of head and body.this is accompanied sometimes with fever on that side only and also difficulties in breathing on that side(my left side is perfectly okey) at night i also sweat on the right side when it started i was going through a traumatic experience though i cannot say that it is the cause.it seems to worsen or get better with time what could be the cause?
