Hi, ive been getting dizzy spells now and then. is it something i should be worried about? also, my left arm feels a bit numb now and then, what could be the cause of that?

Dizzy, arm numbness: Lightheaded attacks can be due to low or high blood pressure, anemia, abnormal Herat rhythm. Vertigo can be from an inner ear disorder or intracranial pathology. Recurrent numbness may be a nerve impingement or vascular disorder in the arm or brain pathology. You should have a medical exam with appropriate testing and a referral to a neurologist may be recommended as well.
