Hi, im male 33 years old, i have this feeling of choking and it feels like someone is holding my upper part of the throat, i dont have difficulty of swallowing any food... relief temporarily by coughing, eating and drinking, as well as relief when i just jogged....so i cough every now and then, during morning, it feels like nothing, but as the day goes, specially afternoon, it getting worst, i have also this feeling that i have phlegm but apparently none, i just spit and all i can see is just white saliva, but sometimes with brownie phlegm and thinking it is from smoking, i stop smoking when i had this choKING feelings... and it feels like somehow connected with back pain... i always have this back pain.. but relief just by leaning my back.
