Carole, I don't think that there is no other group like PT!! EVERYONE here is so understanding and helpful, kind, and is so ready to help people with special issues going on in their life. Like for instance you are getting so many well wishes about your son returning home(I hope Scott comes home safe to give his mom the biggest hug in the world!) and myself for encouragement and advice about my knee. To EVERY PTer that reads this THANK YOU from Carole & david p!!
