I had CTS surgery on my left hand and boy let me tell you. What a relief that was. I still get pains in my elbows but that's because I sleep with my arms bent up. My right hand is has slight CT but not enough to have the surgery. I wore a brace on my left hand while sleeping and it helped but it didn't make it go away completely because I am on a computer all day and I do a lot of sewing.
Good luck, I hope the non-surgery recommendations work for you.
