FWIW, my wife had really bad carpal tunnel syndrome after many years of being a photographer, carrying too many cameras... her hands would tingle and burn, go numb, the whole thing.
She tried Platelet-Rich Plasma (PRP) therapy, which involves injecting your own platelets into the affected area. Her results have been amazing! In about a day and a half just about all of her symptoms were gone and rarely return (this was about 3 months ago). I'm considering getting the therapy for one of my ribs that keeps getting pulled out of alignment due to years of guitar playing and mountain biking having weakened one of the ligaments that should hold it in place.
