Tight Belt Feeling
I have been dealing with this tight belt feeling for a very long time. It is just below my rib cage and has a tendency to come and go. I asked my doctors about this feeling when I first noticed it and they informed me that, indeed, it is a residual of GBS. Since GBS I have acquired a heart condition and the pain and tightness that I have from this problem is much higher in my chest.
Tell your father that I wish him good luck in his recovery.
