What Causes Pain And Sensation Of Something Stuck In The Throat?

Hello. My name is Gan. I had endoscopy in April. After that I had pain on left side of my throat about 2-3 weeks. After it seemed to be OK for a while. But feeling like something stuck on my throat after eating something often happened. Starting the end of May this feeling got worse. Always something stuck and hurt my throat. Now I can not eat solid food. I saw many doctors . I did barium swallowing test, throat soft tissue X-ray. But both testes show everything is fine. I went to voice doctor, who performed massage on my throat, ear nose throat doctor referred me, said my throat muscles are very tight. The massage was very expensive( $180/hour). I don t know if this will help me to get rid of this problem. I am very tired, very anxious. After I tried to eat small peace of meat it feels like stuck in or out of my esophagus, if i try to make it out by coughing I feel it moves up and down there. But doesn t come out, doesn t go down. It stays there whole day. I lost 15 lb in 1 month. I don t know what to do. Can anyone help me. Now I want to do MRI but doctors don t refer , plus here in Canada wait time is too long.
