I had unprotected sex on jan 4th. On jan 28th i saw my doctor and was tested sor all stds my results were neg. my question is would hiv show up in a blood test after only 28 day? About a week ago i was diagnosed with shingles, i was wondering if this is a early sign of hiv? I am also taking humira for psoriasis i have seen that that may have caused the shingles but i get conflicting answers i saw my dr yesterday and again all the std's were neg but i don't have the results of hiv yet. i'm freaking out totally any educated answers would be appreciated
