You’ve developed a strange little numbness and tingling in the fingers of your left hand. It doesn’t really hurt, but it’s just.... odd. Maybe the tingling goes away on its own and you don’t think about it again. Or maybe it sticks around and even starts to slowly grow so that now your forearm is numb, too.
Do you call the doctor? For some tingling fingers....
There are many possible causes of numb fingers. Let’s assume that you didn’t just break your fingers; because if you had, you’d be in the emergency room seeking medical attention.
The numbness could be caused by (but less frequently) by frostbite, leprosy, or rare genetic disorders, such as Haim-Munk syndrome or hereditary neuropathy with liability to pressure palsies.
Do you have diabetes? Pernicious anemia? Hypothyroidism? Peripheral vascular disease? Lupus? Raynaud’s syndrome? Guillaine-Barre syndrome? Cervical spondylosis (aka osteoarthritis)? Carpal tunnel syndrome? Or a pinched nerve?
Maybe you do have a demyelinating disease such as multiple sclerosis (MS) which affects the central nervous system or chronic inflammatory demyelinating polyneuropathy (CIDP) which affects the peripheral nervous system.
