Hi, Well, blood taste is not indicative of anything unless assisted by investigations, in fact it may indicate some problem with your taste sensation related nerve or local oral problems. - Recurrent bleed with history of boxing in past should be well invested as follows to get an exact diagnosis so that a proper and specific management can be done - CT scan of nose and sinuses - Angiogram MRI - Tests of blood like bleeding, time, clotting time, prothrombine time, platelet count - Any other investigations as would be suggested by your doctors - Nasal endoscopy helps many a times to know the cause and local management of any bleeding point if present can be managed by local cauterisation - If needed the last resort would be to go for ligation of the supplying artery as this is now a common surgery Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
