Hi Duane, I'm sorry to hear about your wrist arm/wrist/palm pain. Without seeing your hand position (unless you can upload a photo / youtube clip?), and assuming that your hand position is correct, this could be due to not relaxing.
If you're tense when you play then things are going to start hurting pretty quickly - and that goes for both right and left arms/wrists. Next time you're sat with the guitar in the playing position - but not playing anything - consciously focus on whether you are relaxed. Start with your shoulders - if they're tense they'll be raised, then your back - if it's twisted you'll be tensing to keep it in that position, then work your way down all your muscles from your shoulder > elbow > forearm > wrist > fingers and concentrate on relaxing.
If your hand is indeed in the correct position then it will be in that position now when you're entire arm, shoulder and back are relaxed - if you have to hold it in a position then you are not in the correct position because you won't be relaxed.
So, assuming you ARE relaxed, play a slow P-A-M-I arpeggio on the first 4 strings using free strokes. Are you relaxed? Every movement should be a relaxed movement. If it's not then you are going to be in pain. If you ARE relaxed and you're still in pain then chances are you've already caused some damage to your tendons and the best thing you can do for the time being is to not play with your right arm until the pain subsides. If you're getting pain away from the guitar then that's probably the case. Make no mistake though, if you try and play THROUGH this pain, you could cause worse injury and cause your recovery to be longer.
For the next few days try not to play with your right arm and instead concentrate on your left hand work - hammer-ons and pull-offs and the like.
Additionally, if you use a mouse all day long in your day job then I'd advise swapping it to your left hand. It'll be weird at first but you soon get used to it - you'll be surprised at how much more your right arm will be rested by not using the mouse.
Similarly, if you can, try changing your left-right tasks round for a few weeks. Things like opening doors, brushing your teeth and such like - instead of using your right hand, use your left.
Doing small things like that can speed up your recovery so you can get back onto the guitar quicker.
I hope that helps,
