I recently saw the dentist because I had swelling on the outside of my cheek towards the bottom, the inside of my cheek is a really swollen (it feels fluffy) and I was having pain. Prior to that I saw a general doctor who noted that I had an ulcer in my left nose and an ulcer on the effected side of mouth (right side, left is totally fine) and said my gums looked bad and I needed to see a dentist. The dentist told me the swelling and pain could be from a parotid gland infection, so he prescribed antibiotics that's 1 pill 4x a day. However, when he said that he felt inside my mouth, he said the area I am describing pain and swelling, has "hardened" and that he felt a lump back there. If my symptoms and the lump do not subside with antibiotics I have to see an ENT. Does anyone have any idea what it could be? I should note that dental infection and all other dental stuff was ruled out
