You probably don't want to here this.
I was knocked off in 2015, resulting in a dislocated shoulder with a crack in the joint that required pinning all went well and as the surgeon said it was an easy routine job, there was hardly any visible sign of a scar but swelling appeared and I was eventually referred back to hospital, where the surgeon confirmed an infection and said he should remove the pin, which he did and fitted a drain pump to the wound, this needed changing twice and final removal, I spent 13 nights in hospital with 5 opps, in total, I now have a scar that resembles the Grand Canyon and the shoulder is not functioning correctly.
I do hope yours doesn't turn out to be as serious, good luck.
