I went to the hospital a month ago, done a chest x ray again, it came clear, done colonoscopy, gastroscopy, and upper endoscopy which said my membrane is vulnerable with spotty bleeding at touch, but it didnt explain
blood in mucus. So after that i went to a Sinus and nasopharynx MSCT scan. it showed that my left maxillary sinus is complety full of tissue, which was spreading to the nasopharynx and theres a mass 3cm large and 2.5 wide...they said CT didnt show a tumor or metastases.
