For example, if a person’s actual blood pressure is 134, and blood pressure is measured on a dangling arm, the reading could end up over 140, which is considered to be stage 2 hypertension.
Cheiralgia paraesthetica (Wartenberg's syndrome) is a neuropathy of the hand generally caused by compression or trauma to the superficial branch of the radial nerve. [1] [2] The area affected is typically on the back or side of the hand at the base of the thumb, near the anatomical snuffbox, but may extend up the back of the thumb and index finger and across the back of the hand.
