I am 22 year old female, diagnosed with hypothyroidism. At the time of my diagnosis, they found some nodules on my thyroid but they were biopsied and found to be benign. This was 2 years ago. Lately, I ve had quite a few sore throats and coughs but figured it was due to cold and flu season. I also just noticed in the last few days that I was getting another sore throat but this time, my throat felt swollen to the touch. Still figuring it was a cold, I didn t do anything. But tonight I coughed up a red, bloody clot. Since then, I ve been clearing my throat and finding little traces of red or pink in my spit. Is this something that I should be so concerned about that I should seek immediate medical help? Or do I need to seek any medical help?
