Hi I am 30 years old and have a persistent winter cough - had this for a few years. I have recently been to the doctors about this and was prescribed a steroid inhaler as they think I may have asthma . For the past few days, I have noticed a small amount of blood in my spit when I brush my teeth (at no other time). I can t see where the blood is coming from in my mouth...could this be coming from my throat?
Hi, You need to get yourself evaluated by a pulmonologist/ chest physician. Investigations required are at least chest X-ray, Serum IGE levels and pulmonary function test. The blood can be from your mouth/ due to a dental cause. Please get evaluated by a dentist also (Since the bleeding is only at the time of brushing). If blood is noticed at other time i.e. either prior to or after brushing then there is a possibility of it being from throat or lower down and chances of secondary infection will be increased then. Based on your evaluation your treatment needs to be titrated.  Regards
