I get a pins and needles feeling in my fingertips when i bend my arms. my blood pressure is fine, my cholesterol level is fine, my blood sugar is fine. these were tested. that is the reason for this feeling? what do i need to do or get?

Paresthesia w/ bend: Pins and needles is paresthesia . May be due to disc herniation in the neck pressing on the nerve w/ bending or nerve compression at the shoulder level ( brachial plexus)-thoracic outlet . F/U w/ neurology cervical MRI notes disc, CXR will note chest mass pressing nerve. Rarely may be MS or other autoimmune . cerebral issue.

Nerve pinching: Dr. Gliksman mentions many potential reasons. Bending arms at elbow suggests ulnar nerve, at wrist median, at shoulder brachial plexus. In brief, it is a matter of guessing without a formal neurological exam. Schedule an appointment, and perhaps clarify with an EMG test, and you will likely find your answer.
