what does it mean when your toe starts swelling and turning white underneath? with itching and pain?
sorry to hear you're experiencing this. it must be uncomfortable! it's really impossible to say what could be causing this without a physical examination. your best bet is to make an appointment with your primary care provider and let him or her take a look at your toe. because the range of possible causes is so wide (and depends a lot on your physical history medications and so on) only your health care provider can provide a diagnosis. i hope you're able to get this resolved quickly!
