I have had trigger finger for about 5 years; I have had cortisone injections, but was told I could only have 2, after that it would have to be surgery. I have persevered since my last injection about 4 years ago, but recently the problem has become much worse - I woke up with my finger closed in a claw-like position and it didn't release for over an hour. I have just contacted my doctor and he has referred me to a hospital consultant (all done via email). I presume I will now have surgery. You really should contact your doctor and they will probably suggest an injection - it certainly worked for me, but the effects only lasted for about 6 months, still, better than nothing.
