My ot suggested when spending time with my horse, I pet her using my affected hand and arm and go with and against the grain of her short summer coat. Just kinda using her fur like a brush. It's very nice because for me being around horses just standing and hanging around gives me Very good physiological feedback. Because of this I don't mind doing it and tend to ignore the extent of the bad feeling...
He suggests this to people with pets who have nerve issues and such. (I think I am his only crps patient but he seems to know about it )
If you have pets I highly suggest this! Just don't do it during and excitable time, try it when it's in a relaxed calm environment where you kinda forget what you are doing. But I am not sure how it would work if you have full body pain. but for limbs it would work out
