If it is carpal tunnel syndrome, you can usually tell because you should feel numbness in your thumb, index finger, middle finger and 1/2 of the side of your ring finger. If your ulnar nerve is the cause, then the other 1/2 side of your ring finger and your little finger will be numb instead.
I had CTS so bad that for the better part of a year I had no feeling in my fingertips at all, and had to have my wife button my shirts. I had to use my little finger to dig change back out of the coke machine.
Wrist bracelets made the problem worse by putting continuous pressure on the median (carpal) nerve. Ergonometric positioning at my work station helped but not a whole lot. It's more of a preventative than a cure.
NSAIDS didn't help much.
What did help was the use of Iontophoresis using a device called the Dupel system made by EMPI Corporation. A physical therapist can get the dexamethasone sodium phosphate solution from the druggist (on order from a doctor) and applies it to bandage like electrode patche. One patch goes over the carpal area of your wrist and the return electrode patch goes up near your elbow. Anyway, the device creates a field in the medicated pad that propels the like-charged ions of the dexamethasone into the localized area of the swollen nerve. (Acutally, what is happening is that repetitive use of the hand causes the carpal nerve to swell. It is surrounded on three sides by wrist bones and on the fourth side by the "carpal ligature". The carpal nerve has nowhere to expand, and therefore gets "strangulated", so to speak, thus cutting off the ability to transmit nerve impulses.
Surgery, according to the State person who monitors these things, told me that in about 1/2 of the cases he's followed, the cutting of the ligature, while acutely relieving the pressure on the nerve by allowing it to expand resulted in the ligature healing itself, and the scar tissue that results actually decreased the "tunnel" through which the carpal nerve passes, thus making the problem worse in the chronic situation.
Therefore, I solved my problem with the Dupel system. About three 1/2 hour treatments a week for about 3 weeks resulted in my waking up one day and it was gone. Preventative treatment was to repeat this procedure once or twice a year and I've not been bothered by it since. That was over 10 years ago.
Just my experience, and not to be taken as me giving you medical advice. I am not a physician!
