Angie, I so understand and I empathize and send healing light and love your way. Rest is the only way to heal and muscles and nerves take much longer to heal than even broken bones, I've been told, BUT they DO HEAL.
Please consider sleeping with your arms as straight as possible (I'm a side sleeper and keep them that way, between my legs) and consider using voice-activated typing methods, if you can. A compression band may also help, depending where your pain is located. A rotation of ice and heat combinations, and especially ice may help, too.
There IS a pain-free future, for sure. Now, I honestly hope you're not reading this, because then that would mean that you are resting and away from the keyboard.
