I never had such an experience, other than from a bacterial, fungal infection. Could be from the increased stomach from eating more food? I would see the doctor just to rule out infections too, which are easily treated with Bactrim or anti fungal, each one is different. I washed mine with soap water in the shower, dried thoroughly, used peroxide, and then applied the cream wether it be Bactrim or anti fungal. sometimes I used gauze, under, over, the plate plate, sometimes not, due to bacteria being caused by moisture. Good luck.
