I must have had a really good doctor. He told me it would be nothing & I could go back to work day of. The only real limitations I had was no pool for at least 2 weeks, for me or the "swim team" if ya catch my drift. His suggestion was don't do anything that that made me uncomfortable.
I didn't believe him and expected what you all are describing. I scheduled it for Thurs afternoon and also took Friday off. After the procedure, he gave me a subscription for pain pills. When I picked it up it was 2 pills. Not 2 different medications, 2 pills in a bottle, done. I took one and probably didn't need it. Never took the second. I went to work the next day to save the personal day. (Full disclosure, I had an job in an office setting. I wouldn't have done roofing or another labor intensive job the next day. I would have moved one keg though, not that I am telling you to. Do NOT take any medical or well being advice from me, as I am NOT a doctor).
Only discomfort I encountered was when I wasn't careful when I sat down. No swelling to speak of, no pain, no cramps, didn't need to ice it or use frozen peas.
And 2 seperate tests conducted at a hospital confirmed it was a successful procedure, plus the additional testing in my home "lab".
