My 30 year old son started w/ scrotal pain and swelling & had an ultrasound. The Dr. said all looked okay, but ordered antibiotic & Ibuprofen for epididymitis. He was advised to use ice, rest, and wear supportive underwear. After 2 days of following regimen, his pain in that area has subsided, but now he is experiencing muscle pain in arms & legs and noticeable weakness in his hands. This does not sound like epididymitis. What else could be going on? Could he be having a reaction to abx.?
