From last 2 days I am having pain in my left testicle not in right one. Its not paining all the time. Pain will happen when I press it or try to lift it and the pain is not sever its very less pain. This is happening from last 2 days. Doing any exercise or anything will not cause any pain it's just when I touch it or press it, I feel less pain. I have no problem in urination. I am 18 years old. And I haven't done masturbation from last 3 weeks.
