Linda,
I am so sorry to hear about what your going through. It's difficult when your family and friends do not understand. Support is important. Have you tried sharing with them the information that is available on the web? It might help them understand more.
We have a friend of the family who recently got RSD just from being hit by a tricycle....My sister could not understand how something so minor caused it (she understood my husbands condition - first time being burnt with acid and the second due to surgery - but not hers as it was minor). I shared with her this information (it became a little more clear for her...)

Have you tried anything for the muscle spasms? My husband just started a muscle relaxant (generic form of Zanaflex) and it seems to help when he's taking it - at least he's not spasming and can get some decent sleep.
Know that we are here for you - Any time you want to talk....just give a hollar
