I am 31, and recently began having joint pains in my knees and feet, went in to the doctor who thought it may be arthritis related. I had some blood tests done and I tested positive for what I believe he said was ANH. Unfortunately my doctor was running behind and I didn't get much of a chance to ask much about it, but he gave me more blood work testing for rhemetoid arthritis. But he did say testing positive for ANH could mean a number of things. Later I was thinking about this, would HIV fall into this category? I'm due to be tested for that here, and plan on it, but that thought scared me. Anyone know anything about this?
