Painful tooth lead to excruciating pains in my face. Is this a tumor?
A bad tooth that I’ve been ignoring for quite a while started getting pretty painful. I made a dentist appointment, and had an x ray done and scheduled a root canal for said tooth. After the x ray was finished, I noticed there is an oval above the bad tooth (left side, top molar).
I was sent home with antibiotics (amoxicillin), and 800 mg ibuprofen. The pain in my tooth decreased and I was looking forward to the root canal. 3 days into the amoxicillin, I started feeling a stinging burning pain in my cheekbones, temples, nose, and jaw. This pain was constant and unbearable. 2 days later, the right side of my face was no longer feeling this pain, but the left side (the side with the tooth) still had pain and was getting worse.
It got to a point where I couldn’t open my mouth. I can only breathe out of my right nostril. And my left eye feels like it’s about to pop, and feels like it is poking out. The tooth still doesn’t feel any more pain, just the entire left side of my face. Now the pain started extending down to the left side of my throat / neck. (I have multiple suspicious thyroid nodules on the left side).
I went to the hospital because I just could not handle the pain any longer. They performed a CT scan, and that’s the results in the second picture. They referred me to an ENT to find out what the obstruction is. I’m worried this might be a tumor because of the extent of this pain. Is anyone familiar with this type of situation?
