Hang in there bud it's in God's hands! We all know how the medical field can be....thoughts and prayers for you and your family.
I may be late in the game but never too late to send prayers your way and for your son. Hope all is well when you see the specialist.
I hated hospitals right up until I needed one to keep me alive. Now I merely dislike them. Nurses, BTW, rock like no one else. Prayers for your son.
