So sorry I missed this post but am really pleased to hear that Cameron is on the road to recovery and pain free.
Being the parent of an Aspergers boy (14) I fully understand how frustrating it is trying to get people to understand that what to them may seem a small and logical thing, but to my son is a big deal. Most of the time it is the fear of the unknown for them, and from your sons point of view being asked to take a new medicine would no doubt have been a bit traumatic for him.
Sounds like you have had a rough week and I am full of admiration for the patience and love you have for your Cameron.
Hope all goes well next week and please give him our best wishes.
