I’ve had a sore throat since yesterday, later that night, I used some nasal spray and cleared my throat and there was some blood in my phlegm, is this normal? Are there common illnesses that can cause this? I can eat food and drink liquids just fine, I’d say the pain in my throat is maybe a 1 possibly a 2 at the most.
I wouldn't say it's "normal," but it isn't unusual to have a trace of blood in phlegm with a hard cough or throat clear. Most of the time, it comes from the nose/post nasal drip/secretions. Other times, a small capillary in the back of the throat could break and result in this. Less commonly, with such a tiny amount, it could have originated in the lung.
