1 week and 3 days ago I nearly choked on some food and had to cough until blood came out of my nose. I ate just meat and soft food with Chilli so cannot be bone. But that was only 1 cough. After that I was ok for a few days though feel something is in my throat. 4 days ago I felt a sharp pain in my throat left and right while inhaling. I have visited 5 Doctors and specialists did endoscope but they find my throat fine! I'm very worried and it gives me sleepless nights because I'm afraid to inhale, 20% of the time there is a sharp sensation. Almost like electric shock. But last 1 second only. I feel like there's a lump in my throat. I'm able to swallow and no pain! Pain only when inhaling! No Doctors know what's wrong! I'm really worried!! Help!
