[|Human|] Hi keep getting sore lumps on the roof of my mouth at t back each side that keep coming up & wont go unless i have strong tablets from the doctor, they go down but then the next months they are back up sore again, i find it really sore to swollow, talk when i have theses lumps, what  do you think is causing them to come up each month please.
[|AI|]  Hello, Thank you for consulting with Chat Doctor. There can be two reasons for these sore lumps on the roof of the mouth every month,1. First it can be possible that there is some infection in the upper back teeth, and now it is spreading to the gums and cause soreness.2. Second it can be possible that the bone in the roof in infected and causing this soreness. To get it confirmed you have to visit a dentist and get a full mouth x-ray done which will show the area of infection. Hope it will help you.
