What can I do for itching and redness on my penis? Should I make an appointment with my doctor?

If you are experiencing itching and redness on the penis, it is important to evaluate potential causes such as friction from underwear, changes in underwear material, or using a different hygiene product. It is also important to consider the possibility of a sexually transmitted infection if you have had risky sexual encounters recently. If none of these causes seem likely, a redness on the penis may indicate a yeast infection. In this case, you can visit your local pharmacy and ask the pharmacist for advice on over-the-counter products to help with the infection.
