I m Mark! Age: 31 5:8 150 lbs. As a boy used to suffer from itchy-blisters all over my feet and uncommon sore throat irritations. These symptoms went away as I was growing up..., till recently came back all over my body now that I m 31. Was just wondering... I was recently diagnosed with hives on certain parts of my body such as fingers, arms, belly, back of my body etc... My dermatologist did a bio-lab test to find out what it was. It came back to be hives. So I guess I have had hives all of my life... Moving on... Now: Can hives spread to head of penis (cause blisters on that area) and or cause strep-throat? Are those two even related to the hives problem or is it something else such an STD infection? Yes, I m sexually active and I m very concerned about it... Note: My physician run blood tests on me to check for any STD infection and or HIV. Results come back negative all the time; but those little red spots/blisters on the head of my penis come and go back from time to time and the strep-throat problem does the same even after taking antibiotics. (AMOXICILLIN 875MG) Plz. I need a second opinion or advice... I would really appreciate your help. Anybody... Thanks Mark.
