Hi There,
I cant say whether or not you have a TFCC injury as a scan will be able to confirm/deny. What I can say is that from your symptoms i.e forearm pain and ulnar nerve like sensations is that you have some involvement of your forearm muscles. The key issue with this is that the muscles that control your wrist start at the bony bits of the inside and outside elbow. Have a poke around there and have a feel and you will notice it is quite tender.
If you overload these muscle you can appreciate that it will cause some strain on the origin at the bony bit and all the 4 long muscles attached to ONE tendon so tendon is unhappy and starts to thicken and tighten. This can then cause weakness and restriction at your wrist. It is like doing 100 bicep curls and then your bicep is obviously tight and weakened as it has been overloaded. I suspect this is what has happened and resulting in some of your symptoms (not all) but can amount for a lot of it.
Treatment:
- Suggest seeing phyiso/ acupuncturist or massage thereapist or any one that can get stuck into the muscle to release the forearm muscles.
- Stretching forearm muscles like so:
Keeping elbow straight.
From your history it is likely to have a structural issue whether it be scaphoid, degenerative/overuse TFCC injury or wrist instability. Addressing the muscle issues should (i hope!) reduce some of your symtpoms. Give it 4 or 5 sessions of some deep tissue work to release it and the remaining symptoms will dictate how to go about it although obtaining an MRI is useful and consulting with an orthopod.
Hope that helps
