I had a severe nosebleed yesterday due to my INR to high. I am off coumadin for two days but developed a headache today. Is this normal? It feels like I have a sinus infection but I don t think I do, I think it could be related to the silver nitrate or the trama of having to stop the bleeding in the ER. Could that be it?
Dear, Headaches after epistaxis are very common. It may be primarily related to epistaxis or secondary to treatment to stop epistaxis.  Blood may go into the sinuses and causes headache. It may get sometimes infected and results in discharge from nose.  No worries, it may be ok soon in 2-3 days. Take over the counter painkillers and antiallergics.  Warning signs of headache with high INR- very severe headache going to neck, decrease power in limbs and Chat Doctor.  You will be ok soon. Bye
