Hi, for a couple of months now on my right testicle theres a lump of some sort on the top of it, its pea sized and it dosnt really feel circular, it feels like its connected to the tubes of the testicle. how long will this last?

I assume you could feel your epididymides from both testicle and both should be almost the same except you felt an extra lump on the right testicle. What you feel could be a epididymal cyst or nodule, please see your family doctor or a urologist for a correct diagnosis.

From your description it sounds like an epidydimal cyst. If so it usually stays and remains symptomless and will be harmless. If worried pl see a Urologist for precise diagnosis.
