Yeah, I was having cortisone injections before I had the Keyhole surgery and it was OK'ish for a short while but the pain was back like normal, which is why I had the surgery. Since having the surgery though, I've not had pain management so I might give the acupuncture a go.
I've been back in the gym using light weight's and it has improved a bit, so I suppose it's best to have a stronger shoulder with some pain than a weaker one with pain.
