+1 on the Yeeoouuch. had that done on both shoulders and biceps tendons had to be re-attached too. ICE, ICE, & MORE ICE... and like the others replied here; LISTEN TO THE P/T!!!!

Also it is very important to continue to do the R/C exercises & proper warm up from now on, to prevent having to go through it again.
Most importantly, sounds like you have the best healer of all on your side
