Hugs and best wishes for a positive turnout to his appt.
Thank goodness he is going in, men-folk can be very hard to get to the Dr.
My DH has ulcerative colits and has been dr.'ing since he was a teen, but even so, he lapses into "my meds really aren't helping" and went off of them for a year
I nagged him for 6 months until he finally went in after Christmas and things have gotten a little more manageable. Which in his case is better than the norm.
