I'm 21 years old! I was diagnosed with pansinusitis a year back. My chest xray was normal at that time. Later on I had occasional cough like about a few minutes of cough per day(say 3 or 4 minutes) for about 6 months. So I took another chest xray 6 months back which also came out to be normal. My doctor gave me different medicines and a nasal spray. Later everything had an improvement but I was spitting green mucous in the mornings . Recently a week before I had a flight journey. When I landed , I had a severe facial pain. It went off some time after landing. The next day I got cold and went to doctor. My doctor told that the sinus has been aggravated and gave a course of medicine. Two days back, in the morning I felt an uncomfortable with my throat. I felt like something is sticking to he back of the throat. I tried hard by inhaling hard to clear the throat, that time I spitted out chocolate colored stick particle. That happened thrice in the morning. In the afternoon once again when i tried to clear my throat i got bright red blood along with saliva. The next day my throat was almost okay and didn't had any problem. Today again when I tried to clear my throat hard, i found small streak of dark red blood. I have no cough or headaches. I cough a few times intentionally to clear throat but while coughing i did not coughed blood. While inhale very hard i feel some discomfort in my chest!. I'm worried about my health. Please could you tell me what's happening ?
