Jeannine,
Welcome! I have rsd in all for limbs now and it is related to work. I am a nurse and I was sliding a pt up in bed and they all said it was a neck strain..turned into rsd...the the spreads. Have you had lidocaine injections, they work well on some, plus make sure you don't have a trapped nerve in that ankle.
Off the nurse stuff and on to the welcome. Do you have children or a husband? We all know these things can complicate things. I hope this finds you at low pain,
positive thoughts you way
Jennelle
