Question: My left arm and hand have this aching pain and sometimes numb feeling. I am on genetic Lipitor, also blood thinner and blood pressure medication.

Dr. Hibberd's answer:

Left arm and hand numbness that comes and goes is most likely due to a local vascular or neurological cause. It could be a nerve entrapment or a vessel blockage.

Of course, your pain may also be a sign of a heart condition or even a pre-stroke warning.

My advice: See your doctor now without delay.
