I did go to the OS on call Thursday since I was somewhat worried. It turns out that the lump was my parotid gland. He also said my healing was on the slow side. The sore area is actually above the lump, between the cheek and gum. He said it looked like an ulcer was there, but that everything seemed fine otherwise.
I do go back to the OS who did the surgery this Wednesday. He can check the healing again for me and let me know what he sees. I still have some soreness.
Thanks Bryanna.
