Hi dear , The symptoms you mention in query are very common .There is nothing to worry and blood probably do not come from nose . There can be two reasons for such symptoms . First there can be a infection in oral cavity like gingivitis and periodontitis . In this case you should consult dentist for proper examination . Doctor with the help of a instrument known as probe check the depth of gum pocket to confirm the diagnosis . In this case Doctor may perform oral prophylaxis like scaling and curetage . Doctor may also prescribe antibiotics ( metronidazole ) course and show correct brushing technique . Secondly it can be due to acid reflux . If your have symptoms like heart burn the its a gastrointestinal reflux disease , if there is no such symptoms then its a silent reflux . Doctor may prescribe you medicines like ranitidine and omeprazole . For noe maintain proper oral hygiene , do warm saline rinse , Take antacid and eat light food at night . Avoid smoking and alcohol. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
