I have some bump like patches on my penis head glans. These bumps clearly visible when my penis get erected. I check for std like chalymadia, gonorrhea, syphilis, and hiv ask test results are negative. I also get tested for uti and blood sugar and results are negative. My dermatologist told me this is balanitis and other dermatologist told me this is due to swelling glands or swelling veins. Can you please help me about my problem.
