i would expect some inflammation and swelling but this sounds more than i have seen. i would give it some time as he suggests wear an athletic supporter 24/7 for a few weeks outside underwear to keep it snug -- gravity is not your friend here. also ask your urologist about taking anti-inflammation meds such as celebrex or over-the-counter but high-dose ibuprofen or aleve. maybe even ice up twice a day. stay in close contact with him.
2 months ago i had a penile implant. my testicle sac containing the controls keeps filling with fluid. will it go away?
