First day I experienced toothache and headache so I took pain killer pills. 2nd day , when the toothache subsides, headache remains then I had a running nose, which I think i will be having a flu . Then I took cold medicines, but on 3rd day I got foul smell on my breath which looks like a rotten mucus . So please advise. I don t know what to do, whether to extract the tooth as I still feel pain sometimes and headache still there,
