Hi,I had a vasectomy 6 weeks ago and after four days, I had an infection. This was treated but on Christmas Day, I  had a sore left testicle and now I feel a lump on the vein below my left testicle. I am waiting for an ultrasound but the hospital will not return my calls about when the date is. It is very uncomfortable and I have sharp pains from time to time on my left testicle.
HIT hank for asking to ChatDoctorI really appreciate your concern, this is very common complication being noted in vasectomy, due to the loose skin the infection parts spreads up very quickly and became painful, if I would be your doctor then I would treat you with Ibuprofen with Acetaminophen\" three times in day, I usually prefer Boric acid powder for fermentation, this is to be mixed in hot water (Boiled then bring the temperature at suitable level) the boric acid about 5 gram should me mix with one and half liter of water then pour the water on swelling part, this also give quick relief, have nice day.
