About 3 days ago I barely touched my left testicle and it felt as it had been flicked the pain lasted about 10 minutes went away then came back in about 30 minutes when I walked around. I went to bed woke up and my left testicle has been sore for about 2 days. It is not swollen, discolered, no lumps, doesn't hurt to be touched, doesn't burn when I pee and I would rate my pain only about a 2-3. If anyone can help please do. Thank you
