I have numbness in my feet what could be causing that?

Nerve irritation: Numbness is often a sign of a nerve being irritated or pinched somewhere. Diabetic patients for example get neuropathy. Vascular issues may cause numbness too, such as when you get "pins and needles" in your feet if you sit on them too long etc. If the problem persists, see your dr. And get evaluated and possibly have an EMG to start the diagnostic work up.
