Scared I have symptoms of hiv,a long list. Warts/rash on knee that is very uncommon for me. Abdominal pain lasting 2 months that showed nothing in a abdominal ctscan and only chemical gastritis from upper endoscopy. Somscared it has to be hiv. Also some tingling in random places on foot and knee. Finally some numbness in left arm near under arm that might be lymph nodes. I am a worrier but this stomach thing can't just be worrying. Thoughts?
