I hacked up a real thick sample that was directly from my throat, and spit it out onto a tissue. I noticed a streak of blood
on the tissue mixed with yellow phlegm
. I continued to try to bring phlegm up, and didn’t notice the blood anymore. Then, about an hour later, I once again brought up a real thick sample from deep within and there was a smaller bit of blood (I had to inspect the tissue very closely to identify it).
