Hi, About 10+ weeks ago, I began having a pain in my testicles (I am 16). This pain was accompanied by cramps in my groin, and some pain radiating down into my legs. I went to the doctor and he didn t feel anything abnormal, so he booked me for a testicular ultrasound as well as did urine and blood tests. Everything came back normal. The pain in my testicles began to go away and was replaced by a very sensitive scrotum and what feels like hard/swollen epididymis only after ejaculation. As well my stomach and back began to experience more discomfort. I went back to the doctors again, he told me everything still felt normal and booked me for a stomach ultrasound, which came back normal. I also had a massage therapy and was told all my muscles were very tense. The next day I began experiencing pain in my penis, which has gotten better but is still there. Also recently I ve noticed that the lymph nodes in my groin and armpit appear swollen (possibly because I had the flu last Thursday). This has all caused me a lot of mental stress and would just like another opinion on whether it s stress/muscular, hormonal, infection, or worse.
