Often at times when i eat rice it gets stuck in the bottom of my throat close to my chest , It takes about 10 -15min to push in down with little sips of water. Everytime i sip and swollow small amounts of water to push in down, I automatically regurgitate the water back up as it does not push the food down or pass the food. It happens with chicken too two times but mostly rice. This is happening on a frequent basis now when i eat rice. It only happens on the first swollow of rice, after the rice and gone down i then can eat properly. Just last year at end of christmas i had some sticky flem in my throat which i tried to cough and dislodge from my throat, when i did that i breathed in and the flem went into my lung and i couldnt breath for 1 min at all and it was very scary. i dont know if this has anything to do with it. I smoke ciggaretts as well. about 1 packit of 20s a week
