<s>[INST] Hi, I ve been trying to get to sleep tonight but I ve got a continues numbness in the middle of my left arm between my shoulder and my elbow. When I lye down I tend to sweat and it feels like the pain is shooting to my head and neck making me feel dizzy and lightheaded. It s really concerning me as I ve never felt like this before and I have to tend to sit up because the pain gets much worse when I m lying down. [/INST] Hi, Thanks for your query.
