Swimming at The London Fields Lido

Swimming on a fantastic day in February.  Problems with my shoulder cut the swim short - after an X ray, it transpires there is damage in the shoulder.  If I have torn the ligament, I will need and operation and the swim will be on hold (2 months no swimming and 6 months recovery).  Hopefully, it is just damaged and I can get away with injections - either way, it is very, very painful!
