[|Human|] HI. I am just getting over the a very bad flu and I now have a large lump on the roof of my mouth. The lump is located towards the back of my mouth on the left hand side. It is very painful. It appeared two days ago and is about half the size of a dime. It is almost causing my entire mouth to be sore. (And I am pretty tough when it comes to pain. I have Pudendal Neuralgia!) What could it be?!?
[|AI|]  Lump on roof of mouth can be there because of some trauma to the roof of mouth or can occur because of impingement of some sharp foodstuff there. It can also be a canker sore. Trauma to roof of mouth can lead to pain and soreness and can cause swelling which usually regresses on its own in some time. Sharp foodstuff impinging can also lead to pain and swelling of the area and after removal of impinging stuff, pain regresses. It can also be canker sores which are self limiting. Ibuprofen is an anti-inflammatory pain med and intake of the med must have provided a faster relief. As of now, you can continue with warm saline rinses.
