Can you tell me if on off headache and numbness tingling in hand and leg?

Headache and tinglin. at the same time in a hand and leg especially in one side of the body can mean a central neurologic issue. See your PCP soon, as there are many issues from poor circulation, to high blood pressure, to stenosis of a artery in the neck, and the list goes on. Rule out less severe issues such as migraines, muscle spasm related to cervical discs and other neurologic or endocrine dx Seek evaluation.
