Hi just want to let you know I suffered with this for around 6 years,and I can totally relate as its a scary symptom to have and especially with the weight loss. Mine came after a series of panic attacks.At first it was the lump sensation,then being unable to swallow due my throat feeling like it had lost the swallowing reflex.Its only this last year and a half or so that I have managed to eat "fairly normal".Dont get me wrong,I still have days where I feel like I can't do a normal swallow but those days are now getting less,especially if my anxiety is low.Its awful what symptoms anxiety brings. I lost a lot of weight too. At my worst, i went on a low dose of anti depressant,for about 6 months and it really helped.
