I have been dealing with what we think is an allergic reaction to foods but cannot pinpoint exactly what. ei: this always occurs while eating, mucus will start draining down my throat, will progressively get worse like there is something stuck in my esophagus, can not swallow, the flow of fluids is like someone has turned on the faucet in my throat, if it last long enough will feel it coming out the roof of my mouth. get bad hiccups which only makes the issue more difficult. If I can throw it up it will give a little relief but will continue with the drain, hiccups, etc. I can not drink anything during this process with the hope of breaking up this flow. When I through up it if clear, very foamy and sometimes there is a little bit of food in it, never bringing up everything I have eaten. I have never been able to consistently tie it to any certain food that I eat, most of the time I am fine and then there will be a reaction of some sort. These expulsion periods can last from 30 minutes to 8 hours of expelling fluids and is very draining because of dehydration. I have never been tested for food allergies, have environmental allergies that I went thru the shots for 5 years and have taken meds also. Generally it does not happen in the morning but today I did have a spell that lasted 1 hour, I had greek yogurt with granola and fresh strawberries. these thing I eat on a regular basis.
