Three weeks ago I had protected sex with a female sex worker, she did give me a hand job. Two days later I felt some burning on my penis the outer layer skin. Then one week later I started having strong digestive problems such as heartburn and frequent bowel movement (not diarrhea) each time after eating. Fast forward today now if I don't eat I get severe body shock, such as cramping of muscle, strong headache, hard to talk, distorted vision to the point of having a seizure. As soon as I eat I get better. I have had no fever some night sweats. My primary doctor ran some initial blood work and found everything to be normal. HIV test negative after 17 days from encounter. Still waiting on the Herpes test. Could these symptoms be related to HIV or Herpes? I do not see any lesions or rashes on my body. Please help I'm very worried.

If the only contact you had with the partner is her hand on your genitals, I do not think this is a risk factor for HIV transmission at all. In theory, it could be a way of transmitting herpes, but this too would be extremely unusual, unless she had open sores on her hands. I really think there is another cause to your symptoms that has nothing to do with sexual infections.
