Last night I woke up just after dozing off to sleep. I woke up with severe tingling all over my body and burning sensation in my tongue. At first I thought it was a panic attack but nothing helped. I eventually went back to bed and slept but always waking up still tingly. It is still there this afternoon. Also tinnitus and a full feeling in my head. I put on a vitamin B12 patch which hasn't helped so much as i thought it would. Neck muscles a bit sore. This is the 2nd time this has happened although the first time it cleared up fairly quickly. I am sure it's connected to the pernicious anaemia. It's really horrible. Any suggestions please?
