I wouldn't be too surprised at that kind of symptom. Since CRPS is a nerve condition, we end up feeling all sorts of weird sensations and pains. Be wary of hypersensitivity! I found out a "new" but good friend of mine has bzttled with this for a while, She rubs and gently massages lotion in all the time she said it will help battle the hypersensitivity before it goes out of control. Of course the wicked Mistress CRPS is different for everyone!
I hope you feel better : )
