It's has been 8 1/2 days since wisdom teeth extraction. 1 lower left. 2 upper ones as well as the two extra teeth beside the wisdom teeth. I have been feeling very nausea since that day. Throbbing pain came around the fourth day and stayed until the 6th day. around day four I was feeling dizzy as if I was going to pass out. The wooziness feeling came back the 6th day. I notice a white sac thing on my cheek and it was sitting on top of my gums beside extraction site around day 5. It deflated and pain eased up. 6th and 7th day I noticed yellow fluid then brown fluid. Now today the 8th day, I feel very sick and blood was on gauze pad I use to check for odd fluids. my question is this an infection spreading throughout my body. Should go to oral surgeon, dentist, or hospital.
