I have had a severe headache for 6 days, two days with severe nausea which has eased, thankfully. Yesterday evening I started getting toothache in my top right molar (never had problems on that side before). Could the headache be causing the toothache, they always feel sinusy, but I haven't got an infection, but the pain is much worse when I move my head. Drs prescribed tripans for future episodes (in case it's a migraine) and has given me leaflets to read on preventative medications we can try, if my new HRT regime doesn't help. Or could the toothache (which wasn't there when the headache started last week) be causing the headache? Or, is it a coincidence and I just have a headache and a toothache? I feel so awful and have tried all sorts of medication to relieve the pain and nothing seems to make much difference.
