blood in mouth after sleeping

Hi,  I am 61 and spit bright red blood first thing after a nights sleep, I do not bring up any during the day even having coughed and maybe brought up phlem. I do have a sore thoat most of the time but do not have a problem swallowing food. In march 2009 I stopped smoking after a second heart attack. My sense of smell is now almost non existent, although this is supposed to improve after quitting cigs ?. I have had scans from the chin down to the stomach and all appears ok apart from scarring in the lung from pheumonia 26 years ago. My diet is pretty good and I cycle regularly and am quite active even though my weight has increased by a stone since stopping smoking. I have prescribed drugs including Bisoprolol, Aspirin, Clopidogrel, Candesartan Cilexetil, Felodipine plus I take Solpadol for back pains occasionally. My Gp has been very good and the respiritory consultant has no concerns.     However, I do have worries !!      Thank you in anticipation, regards,  popsical844

Hi, do you still have your teeth?  I was thinking it could be from gingivitis, as bleeding occurs with this.  I would certainly address the persistent sore throat, this should not be happening.  Take care...
