I am getting very painful tingling in my hands while I sleep. I wake up in such pain, my hands feel hot, they feel enlarged even though they are not, and I have to shake and shake them to lesson the pain. I have suffered with Raynauds years ago, but I smoked at the time. I took Nifedipene then. Is there a supplement I could take that might alleviate this? It wakes me after I ve been sleeping 5 hours, and am in a lighter sleep.
