You should get to an Emergency department, in my opinion, and immediately. The fact that you had a tooth removed that extended into the sinuses, some complications already, and antibiotics without any resolution (in fact, it sounds like things are getting worse) makes me very concerned. Your headache, these "spots" as you describe them, and the fact that you are in increasing pain lead me to suspect an infection that is flourishing, potentially within the soft tissues and the bones of your jaw or face. These are emergencies, as infections of these structures can be very bad and very hard to eradicate. They can eventually involve the brain (meningitis, encephalitis) and be life-threatening.
Go to an Emergency Room tonight, and be seen. They will be able to give you a thorough exam, order the appropriate testing, and begin whatever treatment that you will require. But go tonight.
I hope this helps, and I hope that they are able to help you feel better. Please let me know if you have any further questions - I'm more than happy to help. Take care - Dr. Fay
