For two or three days my tongue, on the left side in the back on the bottom, has been hurting... There's been no sores there. Then today a sore appeared, but not in that place. I overreact a lot but this just scared me... Help? Btw I'm 14, I've never smoked or done drugs of any kind, and obviously I don't have any STDs cuz I've never been sexually active, ever. I just want an answer.. Thanks Also: of it helps, I've been really stressed and emotional lately, and I'm on birth control for painful periods and ovarian cysts.
