I don't have any experience with the scs, but many of the members here do and they should be along to give you some advice. Laura has given you some good tips already.
I did want to welcome you here though. I am really glad you found us but certainly wish you weren't in so much pain. You will enjoy the caring members here. I hope you will stay with us and keep posting.
I am hoping your doctor or the technician will be able to help you sort out the problems tomorrow. Let us know how that goes.
