(((doctor prescribed a course of Antibiotics and steroids...which I took for just over a year.)))
Here is your problem, just like i suspected :).
Do you have AIM or MSN as it may be more simple to get a lot of information out if i was talking to you live. I also want to make sure you know that i was not talking about the radiation causing the condition but being an area of concern not related to your current problems.
Let me know, PM me regardless and i will see what i can do :).
