Ive only had this about 4 or 5 times, not in a regular occurence. Tonight was the first time in months. I was lay on the couch and i had some excess phlemgm or spit in my mouth iwent to swallow and i couldnt it was if the reflex had stopped. It lasted about 20 or 30 sevonds and then i could swallow again. Then because of the panic i had a racing.heart and shaking hands.. My mum says its an anxiety thing. I just want any info possible...
