I have tested negative at 6 months but both my shoulders , along my collarbone hurt, all my joints, major abdominal pain, up high on the right side of abdomin. I lost 20 pounds, had shingles, no appetite, sweats. My wife has been fatigued for over a month now, has a dry cough, acne, and is starting to get abdominal pains. I want to be able to rule out HIV but I think I got co infected with Hep C at the same time and it is causing me not to show antibodies on the test. Is this possible after 6 months, I need help
