Well you are one up one me I refused to go back for the second surgery on my shoulder.
The surgeon gave me about a 60% chance a second attempt was going to work but recovery from the second bout would take longer. I was 4 weeks on morphine tablets, 10 weeks in a sling and 6 months rehab only to find that the tear was not the only issue. During recovery I had 6 hydros because the MRI's kept telling them there was no issues and all that was needed was a hydro to free up and expand the joint. Yet by the time the second surgery was spoken about the surgeon was still not entirely sure what the problem was because the MRI's were inconclusive.
6 years on I can lift things like cement bags, shopping etc but I still can't do repetitive movements, I still take pain killers every now and again, although I've just learnt to live with the pain rather than take tablets but I still don't regret not having the surgery given the chances and the fact that they never found further issues after they repaired the labrum.
I remember seeing the stats from the surgeon before surgery that said Frozen shoulder only happens in 8% of cases. Because I was desperate to get rid of the pain in the first place I accepted those odds but it wasn't until after surgery that I realised their figures were for total frozen shoulder, the figures for partial frozen shoulder (which covers 1% loss to 99%) after surgery are actually up in the 80% area.
I wish you the luck I never had. But if you don't get it, fcuk it life still goes on.
