Hi, Ive been having a bad toothache for a couple of weeks accompanied by a slight headache/jaw pain on the same side. The past 2 days, I had nosebleeds. Not too severe. It stopped about 5min after.  Could everything be due to the toothache and headache? Could it be a sinus infection?
Thanks for your query, I have gone through your query. The tooth pain, headache and jaw pain can be secondary to tooth infection. Particularly this kind of pain comes from the wisdom tooth infection or an impacted tooth. Nothing to be panic, consult an oral physician and get it evaluated. Meanwhile you can take a course of antibiotics like amoxicillin and metronidazole(if you are not allergic) for tooth infection. You can take diclofenac for the pain. Regarding the bleeding from the nose, it can be because of the respiratory tract infection or trauma or secondary to hypertension. Consult a ENT surgeon and get it evaluated. I hope my answer will help you, take care.
