My old old GI didn't think I needed infusions, because "10.0 hg is good enough for you." So I went around him and asked my primary care doctor to refer me to a hematologist. I lied and said my GI thought it would be a good idea
. I got the referral, and the hematologist got my hg back to normal.
Thankfully, my old GI sent me to a hematologist without me even having to ask.
