For the past 8 years I have struggled with lack of sleep due to chronic pain from service connected conditions. I can go to sleep but cramps and spasms wake me up in severe pain within 2-3 hours consistently and I can't go back to sleep! I rarely sleep more than 3 hours at night and sneak in a few half hour power naps in during the day at some point. Every few months I hit a week or two cycle of getting 6-7 hours a night and then right back to the 3 hours a night problem~ This is well documented in my medical records at the VA but with no success at treating it with sleep or pain meds. If I filed a claim, how is this rated or what code is used with the VA?
