I handled workers compensation claims for 35 years. The bet advice I can give you is to see a hand specialist. A neurologist or plastic surgeon who specializes in CTS is best. Stay away from chiropractors, I have never seen a positive result from them. An ortho that is a hand surgeon is also good, but often rush to surgery. If you are at the beginning it is possible they can get the inflammation down. The typical treatment in our neck of the woods, has been using the splints and anti-inflammatory meds. It is necessary to follow dr's orders because the inflammation can be minor, but will flare again if you stop the meds too soon.
If there is no improvement they will talk surgery. But there are a lot of cases where surgery is avoided. So hopefully you have a good doctor.
