1) Rx Carpal tunnel

You have to first check whether it is Carpal tunnel Syndrome or not-

I have worked in NIMHANS and many times we had patients mis-diagnosed carpal tunnel when it was either cervical Wikipedia reference-linkspondylosis or Wikipedia reference-linktennis elbow with the tingling sensation down the fingers, in case you plan to do a NCV it might be useful instead get a xray done of yr neck or get a physio to examine your wrist and do a tinel's sign- test
Are you a diabetic ? it could be diabetic neuropathy also
it can also be a pressure on nerve similar to TOCS

take ultrasound pulsed mode over your carpal bones you ll feel much better

2) Rx TOCS

it is an RSI or seen by birth, have you confirmed the diagnosis ?
an Wikipedia reference-linkMRI should help you out to confirm, usually a Clinical test Roos is effective in diagnosing the condition.
did you get an Xray done ? Any cervical ribs present ?

Additional Comment I forgot:
surgery has its own advantages and disadvantages, just confirm the diagnosis before surgery,think and get yourself examined before the surgery..

use a cold pack, and give lateral glides along and then Pa glides to reduce pressure off the nerve for carpal tunnel .

Use a hot pack place it on the upper chest on the side of the pain,and ULTT will give u relief,
Non medical terms Start with bending head towards the side of the pain and touching your ear with the arm on that side, then hold 5 secs,
Bend your head on the other side and Stretch your hand straight on the side at app 90 degrees hold 5 secs

Hope it helps
