### Patient: Hi doctor, I've been experiencing frequent urination, groin pain, and pain in my testicles. I recently found a lump on my leg and noticed swelling in my scrotum. Do you have any idea what could be causing all of these symptoms?
### Doctor: Yes, based on your symptoms it sounds like you may have a spermatocele, which is a fluid-filled cyst that develops in the epididymis. It can lead to swelling in the scrotum, pain in the testicles, and sometimes cause discomfort in the groin area.
