I've been suffering from a lot of elbow and forearm pain lately, and apparently it's caused by my arms and elbows constantly pressing against the desk.
My doctor says I'm damaging the nerves on my elbow, and if I don't use elbow pads (or spend less time with the computer), it will get worse, and I will be risking permanent damage to the nerves.
Since spending less time with the computer was not really an option, I purchased a pair of these:
They didn't arrive yet, and I know they will probably make me look like a total idiot (my girlfriend has already started making jokes) when they do, but health comes first.
Anyway, my question is: do you use any protective gear while programming? If yes, what do you use?
Thanks,
UPDATE:
Seeing how this question still gets comments after more than a year, I think I should give an update.
First of all, my elbow pads never arrived. Turns out the retailer didn't really have them in stock, so they cancelled my order.
After reading the answers here, I decided not to place another order and considered other options. I rearranged my desk, adjusted my chair, and started giving myself breaks from coding (sometimes an hour, sometimes a couple of days) once I was done with my master's thesis. Earlier this year, I also started going to the gym for the first time in my life.
In the end, I'm happy to report that I no longer have any elbow pain.
Once again, thanks to everyone who has responded.
