Hello Doctor. For last 6-8 months i am experiencing, body rashes , severe itching all over the body, which includes Head, arms, thighs, lower back and sometimes bumps on the forehead . I sometimes get itching on the tip of the penis and around the testicles. Is this a sign of HIV virus or Cancer? I did take Claritin and Aerius medicines but after taking them i get relief for 10 days - but again the itching rashes starts 9-10 days after taking the medication . Lets say i take medice today, all rashes will come back after 10 days. Especially after taking shower it rashes the most. Please advise as ur help is very much appreciated. AAA
