Hello my name is Chris and yesterday I went on a three mile run and shortly after I returned from my run my right testicle started to hurt and feel as if it were swelling up and since I was at work I didnt have the chance to look at it right away, once I finally got home I examined it and noticed that it was significantly larger than my left. It was also sore to touch, I guess my question is what may be the cause of this and should I go see a doctor in person or should I wait a couple of days?                                                                                          Thank you                                                                                              Chris
Hello Chris. Thanks for the query to Chat Doctor. Sudden swelling after three miles walk may be due to.1 Epididmo-orchitis i.e. inflammation of testis, this is the most common cause, so consult a physician and get his opinion as physical examination is important.2 Trauma due to walk you may get injury as testes are very delicate and soft structure so very prone to injury. Take rest for 2-3 days and massage with ice. Simple Tylenol like tablet will provide relief. If swelling and pain increase consult a physician. If after rest swelling and pain reduces, wait for 2-3 days. Good luck.
