my penis tip has become red . i feel burning sensation all the time except while urinating . it only pains when i wear jeans . the penis seems to have swelling . problem is since last 1.5 months . i showed to a dermatologist . he suggested some medicines (muforce 3 kit , unikind K M , microdlox-LBX ) and a cream ( 3 mix ) . i finished the course . but the problem is still the same . and i feel painful in walking and even when i simply sit in my jeans . i dont feel the sensation while peeing but it gets increased when i hold urine for a while. i hope u can suggest me the right thing . and which doctor should i consult.
