I feel the despiration in your voice..and I am sorry.. It is possible your RSD has spread.. please try to relax as the stress is not good for your symptoms.. when you can, please call your treating physcian in order to get in and see them..Possibly they can determine what is happening and set a course of action or even increase your pain meds..Most of all, give you piece of mind.. You have our support.. we all sympathize with your pain and concerns..we can relate and want to help you.. Try to get a good nights rest..don't not use ice on your painful legs..warm bath.. and when you wake..call your Dr..
Rest my friend..
Hugz, Kathy
