Hi,
A red rash on the testicles and penis, along with pain and swelling, could be a sign of a few different conditions. You may have an infection, such as a yeast infection, balanitis (inflammation of the foreskin), or a sexually transmitted infection (STI). It's also possible that you have a skin condition, such as eczema,
psoriasis, or
contact dermatitis.
The fact that you have varicoceles, which are enlarged veins in the scrotum, could also be contributing to the discomfort and pain you're experiencing. Varicoceles can cause a feeling of heaviness or aching in the testicles, and can sometimes lead to
infertility.
It's important to see a healthcare provider for a proper diagnosis and treatment plan. They may recommend a physical exam, blood or urine tests, or a
skin biopsy to determine the cause of the rash and pain. Treatment may include antibiotics, antifungal medication, or other medications to manage any underlying conditions.
