Do not have carpal tunnel but have had cortisone shots for other problems (bursitis, tendonitis) and they worked. Always a good idea to try a treatment like that before considering surgery. Nothing but time to lose.
If your neuro is anxious to cut I would get a second opinion as well.
If it were me I would go for the shots and see if there is improvement. Isn't physical therapy recommended for CT? I had bad knee and hip problems years ago and cortisone and PT resolved the problem 100%...better result than I could have expected from any surgical option.
