Haven't had SRS, but I did have a vasectomy. And that hurt like hell. For two weeks afterward. Granted, I was a dummy and didn't call my doctor for any pain meds. I could have used them. Really, it varies for each individual. Some bodies are more reactive to trauma than others. I know I swell and bruise terrible after surgery. Other people, after a couple days, it's like it never happened. I'm basing my pain and swelling expectations on the reaction to my past surgeries.
