I've had mine even longer. Much longer. I have been offered an operation, but the surgeon admitted that only 60 percent of operations for this are successful. 20 percent give no improvement, but you still hava a scar. The rest make it even worse. I thought those odds were so bad, I refused. I just make sure nothing touches that area - no keys in pockets, no sleeping on that side - now I have no pain unless anything actually touches it.
Physiotherapy made no difference, acupuncture was no help - but some people get relief from some of these treatments.
