Incision has a blister on it ???

It looks really good but in one spot it looks like a blister.  Theres still glue on it but I am putting neosporin on it, gonna call the doctor tomorrow.
Other than that doing pretty good.  There is also a knot or swollen area right underneath my incision.  Not on it...... below it and right in the center of my throat.
What could that be ??   Just swelling or what ya think ?
Still no coke or anything with acid, soft foods but getting better.  TIRED I am tired going to call tomorrow to see when I start the B-12 that should help.
OK THANKS for any info.

Glad to hear you are doing pretty good!  Sorry, I don't know anything about the blister.  The not, either.  My little incisions from gall bladder got knots around them, but they were phlebitis.  Get it anytime I have an IV also.  Hope they are nothing major.  Praying for it to be nothing and recovery to go quickly!
