Hi Minnie,
    I had that in the first year of treatment. I actually was concerned about my ability to swallow at times. It will pass;)
 

I never had tightness in my throat but I did often wake up during the night feeling like I was choking, I still get it sometimes mainly when my throat feels dry.
 

Totally have had this. It's just another form of die off. I had sore throat for like a month, and than one day it just went away. Ya it's weird how you feeling like your throat is so tight, but I told Dr. M and she wasn't surprised that i had this. So it will pass. 

I had this swollen throat thing along with the terrible nausea and throat mucus around the two year mark. Mine lasted about eight months, but eventually did clear. I constantly felt like I was gagging and couldn't breathe, which would sometimes send me into a panic. It turns out it was a healing crisis - junk leaving my body through the mucus, which irritated my throat. Also, the mucus globs getting caught up in my throat contributed. It does pass.. it lasted a long time for me, but I've heard of others having this for a short time.
