Hi, doc. I'm 29 and recently started having weird symptoms. They are mostly in my hands (very tips) and feet. It's tingling and occasional stabbing sensation, and at times itching sensation. It also feels like there "ants crawling under my skin". It seems to be under the skin and I don't have any sensory changes. The symptoms happen when I'm still or at night when I'm in bed. Actually, they mostly happen at night. They are getting worse as I can't sleep at night because of these symptoms. The nighttime is just like nightmare to me. Also, I noticed I started having muscle twitches/fasciculations at night, mostly in my calves and thighs. I don't seem to have any weakness, though. What can this be? I'm so concerned. I've researched B12 deficiency, MS, peripheral nerve hyper excitability. Can you please give me a piece of advice?
