Hi Guys, I am new to this forum and have probably posted in the wrong spot - sorry if i have. I have been reading a lot on this forum and you guys have done a great job with a lot of information. I notice that most peoples immune system problems seem to be with an underactive immune system and with them catching every illness that goes around. For the past 15 years my immune system has been overactive with very very high autoimmune antibodies against my thyroid, the hormone levels have tested normal but the antibodies have been very high. I on the other hand seldom get sick with the flu or a cold. The only flu like symptom i get is a sore throat that never really gets worse - it just flares up when i am stressed or tired which is most of the time. I was wondering if anyone else has had their immune system behave the same way. Also not sure how the XMRV would fit this profile as i understood it to involve the immune system but more so with underactive immune system. Any comments would be much appreciated. Thank you.
