I tested negative 2 weeks ago (2 month window) yet I have a burning sensation in my feet and hands. Could this be related to HIV seroconversion. Did I test too early or is this related to something else.

A burning sensation in your hands and feet could mean a lot of things. One symptom of diabettes is a tingling sensation in the hands and feet. You might want to get a test for diabettes instead. Since your 2 month test for HIV is neg(-) you probably do not have it. Get tested again at 3 month past exposure just to make sure.
