Coughing up blood
2 weeks ago i coughed up about 1/2 a cup of blood. Since then I have been coughing up blood every day. It hasnt been often or a lot of blood but it has been regular. I have no other symptoms apart from high blood pressure for last 18 months - avg 150/90. I have been on blood pressure tablets but they dont seem to have done anything. If anything they have increased my blood pressure. Recently (after the coughing up blood) my doctor has changed the brand. I have had a stiff neck and spasmodic headaches. I thought this was due to mu boxing classes. I also suffer from sinus (self diagnosed) but my doctor doesnt think this is related. I wake up with a blood taste in my mouth. I have had a CT scan and had sputum samples analysed. The CT scan showed a 1cm right hilar lymph node but nothing else. The sputum samples showed no evidence of malignancy. Today I sneezed blood - not much but pure blood.
I am seeing a specialist next week but I was wondering if anyone had any ideas. Particularly if this could be related to sinus?
