Hello, about 30 mins ago, I tasted blood in my mouth. So I went to spit, and a small bit of blood was in my saliva. I also have chronic swelling in my nasal passages, which I am on saline spray and antihistamines to address. Not sure if this is related to the taste of blood, but thought I d mention it. I am panicking in fear that it might be internal bleeding. I also sometimes have a weird pressure in the back of my head and shooting pains in my left temple. What could the problem be?
