Suggest Cause And Remedy For Sinus Inflammation

I am a 54 yo white male and I am worried. 10 weeks ago I had a few drinks and used a used safety razor in the shower at a massage parlor (all women giving massages). I cut my neck shaving. At 8 days my biceps and triceps began aging-my thighs slightly too. My sinuses became inflamed and cleared up in abt three weeks. My muscles have improved byt now at 10 weeks still are a bit weak. Today my sinues just became inflemed again. I have had a temperature slighly beloe normal (98.0) for a while now. I had an HIV rapit test @ 6.5 and again at 9 weeks. Both were negative. I had a Hep ABC screen done with liver enzymes @ 4 weeks by my GP negative and normal. Here are my questions:

1. should I get tested now for antibodies or wait for 12 weeks? The PCR test is expensive.

2. Based on the facts above-what are my chances of having Hep B or C?

3. If not Hep, what other illness could this be please?

Thank You
