I am 64 i am 6' and weigh 215 pounds, i am in great health. i have some puffiness just under the head of my penis in the foreskin area. there is no pain. there is no change in my urine habits. i experienced this a long time ago. but this is the first time in over two years. will antibotics work to resolve this issue. it usually takes a couple weeks or so to go away. i do not have any veneral disease. what could it possibly be?
