Its been 2 days now and my tongue is numb! I have no idea why, I never went to the dentist or anything. I only had a very bad cough, I even think I scratched my throat! But its not like I haven't had it before that it's the cause of my tongue numbness. What do you think is it from a cough or is it caused by something else? (P.S I'm 34 year old female)
