Carpal tunnel endio one year ago doc said scar tissue on nerve left hand and it will go away, told me this in oct my primary doc took xray said fine hand goes numb, feels weird can this be fixed?

EMG: In these cases, a follow up EMG will objectify whether re-innervation and healing is occurring allowing decisions for further treatments. A plain X-Ray will NOT assist in visualization of carpal tunnel pathology but an MRI might. Discuss with your hand specialist

You need to see: A hand specialist. The question is a bit unclear. If you had the surgery already and are still having issues and the surgeon is not addressing them see another hand specialist. An xray is worthless. Carpal tunnel usually has nothing to do with bones as much as soft tissue causing nerve impingement. Scar tissue is not seen on xrays.

In some cases: A nerve may have had chronic changes before surgery orchanges in response to surgical scarring that prevent the nerve from improving. This is a complex scenario that is very different and specific to each event and there is not a single answer that one can give. Much depends upon age, health, time of symptoms and degree before and the immediate vs late effects rx and never exactly the same

Depends: It depends on why your hand goes numb. Sounds like you need an emg/NCS to assess your median nerve (the nerve that travels through and is compressed in carpal tunnel). Ideally this would be compared to a study performed preoperatively. That can assess for recurrent slowing, possibly from scar tissue. Ultrasound is another diagnostic option
