I can feel no lumps on my testicles, but the tube that runs from my left testicle seems to be a little swollen, but I'm not sure. I was wondering if you could tell me what might be the problem and what I should do. Dear Jim Thanks for your question. This is a typical presentation for epididymitis. You should see a doctor for a urinalysis and urine culture to confirm the diagnosis.
Antibiotics is the cure.
Sexually transmitted forms of epididymitis is treated with different antibiotics and your partner needs treatment also. Pain should greatly improve over the next 3-5 days after antibiotics but the swelling may last a month or so. Epididymitis drops way down the differential diagnosis if one has had a vasectomy. This is a medical emergency because surgical correction of a twisted cord is needed within six hours to save the testicle. It is more common on the left side.
