Hello dear! I have gone through your query and understood your concerns! Nose bleeding may happen for too may reasons. I m trying to explain the most common conditions which cause that: - High blood pressure, which damages thin capillaries inside the nose. - Low platelets in blood which makes more possible the hemorrhage to happen. - Allergic conditions or nose infections - Hight temperature and dry air exposure for a long time. This are the most common causes of epistaxis. I would suggest to do the following analysis to find out more details about your health condition. - Measure your blood pressure several times a day, and especially in the moment of bleeding. - Do a complete blood count to see the levels of platelets. - Avoid dry air environments and high temperatures. I hope you will be fine! If you are satisfied form this answer please kindly rate it as helpful and write a review. Sincerely, DR ERIOL.
