Thumb surgery

I had left thumb surgery for osteoarthritis 7 yrs ago which went well,don't get full strength back but no pain so that's OK.had right thumb done 2 yrs later which was OK for a while although took longer to recover.Now I have so much pain in what I think is the scaphoid area into my wrist.The surgeon had me get a shot around the scar area which is not where the pain is and about a yr later it's still as bad if not worse.I am right handed which doesn't help.I have been wearing a wrist/thumb brace and now I have a bruise or broken blood vessel where the shot went in that won't go away. It was a plastic surgeon that operates on hands here in BC,Canada .My question is should I seek a 2nd opinion form an Ortho ? I can't hold a glass,can't even pat my pillow as it's so painful.
