Pain in the penis after a previous bump or infection can happen for several reasons, even if the bump has disappeared. The thin skin you are noticing may be due to healing after inflammation, irritation, friction, or the effect of the cream that was used. Sometimes the skin remains sensitive for some time after healing. However, new pain after a few months should not be ignored, especially in the genital area. Possible causes may include residual inflammation, mild infection, friction injury, nerve irritation, fungal infection, urinary infection, or, less commonly, a sexually transmitted infection that needs reassessment. Since there is no visible bump now, the problem may not be serious, but a proper examination is still important to identify the exact cause. Avoid self-medication or applying multiple creams without advice, especially steroid-containing creams, because they can thin the skin further and delay healing. Keep the area clean and dry, avoid excessive rubbing, tight clothing, and sexual activity until the pain settles. Drinking enough water and maintaining good hygiene may also help. It would be better to consult a dermatologist, STD specialist, or urologist rather than only a general physician, because they are more experienced in evaluating genital skin problems and related infections. Seek medical attention sooner if you develop redness, discharge, burning during urination, ulcers, swelling, fever, or worsening pain. Early evaluation can help reassure you and ensure proper treatment if needed.
