I am 68 nearly 69 and suffering from numbness in arms, legs and face. Also sudden periods of sweating even while just sitting watching TV. I have been to the doctor and have had bloodwork and x-rays on hands. The diagnosis was slightly high cholestorol (no meds prescribed). I have always been fairly active. I get dizzy when I look up and bend my head backwards probably cutting off circulation?? I have have difficulty getting to sleep the last week as well. I don't dring coffee or other caffeinated beverages in the evening. Can you help me
