I have recently had weakness in both arms while I hyper extended my head.....had my head in hair stylists sink. Could not pick my head up. This was followed by weakness and numbness in mouth and jaw. Since then, have experienced cold and tingling in left side of face; not every day....just on and off.  Do you think this a nerve problem?
Hi, Thank you for posting your query. It is a neurological problem. Most importantly, you need to exclude a brain stem ischemia (lack of blood flow to brain) due to dissection of vertebral artery. Another condition to exclude is compression of neck nerves that supply the upper limbs. Please consult a neurologist for evaluation. Best wishes, Chat Doctor.
