Is it Reflux?

 I had surgery in Nov, band adjust in Dec.  Now I am starting to have an acid burning in the back of my throat.  Is this Reflux?
It doesn't bother me when I lay down.  I just get uncomfortable a couple hours after eating dinner.

Sure sounds like it to me.  Follow all the rules for reflux prevention, and report it to your doctor pronto if it doesn't resolve. Could be a sign that your band is a tad too tight for you right now.  That can happen even without a recent fill.

I also had burning in my throat but only after I would drink something. My surgeon had some fluid removed and it stopped. I did get after the fluid was taken out but I haven't had it recently.

I've had my band going on 6 years in August. I'm trying to get a revision done from band to sleeve,

Talk to your surgeon about it.
