Hello Rachell,
If its still causing you difficulty and you've tried injections then surgery is the way to go. I don't have much experience with TFCC injuries but I would imagine it would follow a similar timeline, etc as meniscal surgery (structure in your knee somewhat similar to TFCC). If so your probably looking at 3-4 weeks before you have full use of it again but after 2weeks you should see improvement. A lot will depend on how bad the tear is, where exactly it is and what other structures are damaged. The surgeon should be able to tell you all this.
I would like to know what absolute crook of an accupuncturist took your money and said it would fix your TFCC tear! I'd have time for alternative therapies in general but thats just taking advantage!
