Hello and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
With your given history of
reflex sympathetic dystrophy, it is a clinical syndrome of many unknown causes like minor traumas, infections, surgeries, with an unclear course of pain attacks, vasomotor dysfunction, strokes, characterized by pain, swelling, and vasomotor dysfunction of an extremity.
So don't worry this syndrome is a bit rare, your
back pain and swelling is co-related to your ankle trauma. I don't think there are another complaints. If you early diagnose the RSD you may ask your physician about a sympathetic blockade with anti inflammatory drugs as a first line of treatment.
Sometimes surgical sympathectomy is needed if there is
spinal injury for your back swelling and pain. If you are unable to do your usual normal activities or reached late stages which I think and hope you are not you may use spinal stimulation ( Epidural
implantation of a
spinal cord stimulator which has been shown to provide significant, prolonged pain relief and functional improvement) only if needed or after at least 6 month of
chronic pain.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Ahmed Aly Hassan
