I have been experiencing leg pain in both legs for sometime now...about 2 weeks after unprotected sex. The pain still exists as of now and has been for about 5 weeks now. One day i noticed my legs starting to tingle below the knees...this was followed by shooting pains in my ankels and my toes. I some days also have pain in both knees and a feeling of weak legs. Last week I have noticed shap, shooting, pains in my arms. I just wanted to know if this sounds like PN (or anyway related to hiv infection) and does it start so soon after a possible exposure? I have taken a blood test and will get my results midweek. I was just anxious and nervous waiting for my results.
