I have a Lump on the left side of my cheek after Buccal fat pad Removal. I had the procedure done 9 days ago.

The buccal fat pad on my left cheek was a little stubborn to find at first but besides that the procedure went well. The Dr stated that my left cheek would swell up more than the right because of that. After the fifth day I started to notice a tight pressure like feeling on my left cheek. Dr said it was normal for the lump to occur and that I may have Hematoma but that I didn’t need to get it drained. It’s been 9 days now and the lump is still the same size but now instead of sticking out of my cheek, it is poking in words into my teeth and gums. It’s still tender and now I’m starting to feel a slight pain on my jaw line close to my tonsils. I’m a little worried. Should I let it heal on its own or should I go to the E.R?
