Blood in spit?
I have bad allergies and sinus problems (had surgery in 2004). I am just getting over a chest cold (my entire family is sick with it), but some weird stuff has been happening...
A couple of weeks ago, I took a antihistamine/decongestant before going to bed, and woke up in the morning with an extremely dry throat, mouth, and nose. I went to the bathroom and discovered I had some blood in my spit. It lasted for a few spits and looked like it was all collected on the tongue--I wasn't coughing it up, and when I tried to pull some phlegm from my lungs, the only thing that was produced was some mildly yellow phlegm--no blood.
Then last night, I woke up with a super dry throat, mouth, and nose again, and the same thing happened, although there was much less blood this time. I feel pretty good (chest cold is about 95% gone), and I'm not coughing anymore. So I am little perplexed. This has only happened in the morning after sleeping.
I am 38, in good shape, and a non-smoker.
Has anyone had something similar to this? Is it sinus related?
