I am experiencing a nosebleed from both nostrils with a BP of 138/104 and 99 pulse. Pressure on my nostrils has restricted the bleeding from my nostrils but now can feel blood trickling down my throat. Have had two large blood clots, one from the right nostril, the other coughed up.
Hello, Yes higher blood pressure can cause nose bleeds, because these are thin vessels and poorly support.  Particularly the diastolic BP reading of 104 is significant.  Also, when you close the nostrils, do remember that there are similar two opening of nose in the inside where it communicates with the Oral cavity, hence the tricked and blood clot while coughing.  Control of blood pressure with antihypertensive medication is the key and definitive treatment.  However, as such It's important to rule out local cause in the nose cavity, and some investigation like platelets / coagulation profile so we don't miss on anything.  Tide over treatment till the blood pressure is controlled, is as you have done stuffing of nose and tab trade 500 mg may be given (may or may not benefit) Regards Chat Doctor.
