Tingling Feet

I don't know if I should be concerned or not, but my feet have started tingling, no pain, and not the needly feeling like when we say "my foots asleep". I took some over the counter flu meds yesterday and at times my face as well as my feet felt tingly. I haven't taken any more of the flu medication but my feet are still tingly today. I am 75 pounds overweight, do not take any medications, do not have high blood pressure, diabetes, heart problems or even high cholesterol. Any ideas?

Thanks for your help.
