If he reads this forum or someone has a "in" with him, tell him to look into Low Level Laser Therapy (aka cold lasers) in addition to chiropractic for the CTS. The use of lasers is becoming a very hot topic (haha) in "occupational medicine" these days. Use of it for things like CTS, along with chiropractic care (which works good for CTS as is) is extremely promising. GM did a very large CTS study using cold lasers and they were floored. Recovery was something like 70%+ better with the cold laser added to the regimen. Google should show the study. Anyway, best of luck to him, and definitely try the methods I mentioned before surgery because there is no going back from it, so he may as well try everything non-invasive/conservative first.
