I am a 48 year old male with a history of sperm building up next to my left testicle. 3 days ago, I woke up with severe pain and some swelling in my scrotum. The pain was so bad that I couldn't stand to even touch it. The next day, the swelling had increased to softball size, but seemed to recede as the day progressed. I decided I needed to move around to increase blood flow. The pain, which had also receded overnight, became increasingly worse. Today, I woke up to almost basketball sized swelling, and unbelievable pain when trying to stand. If I lay still on my side, with them laying on my leg, I feel almost no discomfort. There doesn't seem to be any discoloration. Can anyone help?
