I just want some of your opinions. I've been having arm/hand numbness & tingling off and on for a long time. Last night I couldn't sleep for my left hand tingling and my head feels so funny. It's hard to explain. It feels like its going to blow up or something. I'm dizzy/woozy feeling. I don't seem to have any sinus problems. I've been doing a lot of things that have been hard on my neck and back and wonder if this is the result of that? Have any of you felt like this and found out it was from your neck? I just find it very unusual that it kept waking me up feeling like this. Any info will be appreciated. I hope you're all having a good day.
