What causes tingling sensation and numbness in the right arm and fingers?
Patient: for the past 3 weeks I get pins and needles a tigling feeling in my right arm that starts at my shoulder and runs down to my fingers and then my fingers fel numb and my entire arm feels heavy. it happens more when I lean with my elbow but it also happened out of no where as well? Doctor: Hello,  The pain & tingling that you are experiencing in your arm is due to compression, irritation, damage of the peripheral nerves. Peripheral nerves can get affected due to diabetes or any other developing pathology. Visit ER or see a Neurologist, get physically examined and get all the tests for the developing Peripheral Neuropathy done. In the meantime take vitamin B with folic acid, take diet rich in calcium, iron and minerals. For pain take Acetaminophen (Tylenol)when needed.   Hope I have answered your query.  Let me know if I can assist you further.
