Hi i?m a 35 year old male, i?ve had problems with my throat. Sometimes it feels like something is stuck in there, things after i?ve eaten sometimes don?t go down properly, there is a bit of blood in mucus every morning but just a small amount and it?s just the first spit of the day where there?s blood, I have had an ultrasound on my throat and it came back clear, also had a chest x ray and it showed post inflammation from covid but they said it?s all good. I?m waiting a few weeks for an endoscopy but haven?t tried antibiotics yet, I tried yeast infection medications but they did?t work. What could it be.
