Daughter had RSD left leg about 12 years ago.She was 14. Hit back of leg on diving board, small bruise, next day called to school and leg had "blown up" to twice normal or more.

She had epidurals, pt. tens, 3 day fentanyl infusion in hospital etc. until a doctor friend informed me his partner had started a new pain clinic.

New doc had her on a portable infusion unit infusing fentanyl into her spine 24 hours a day. One week on. One month off. She did this for two years and the "monster" always returned.

Sometime after those two years the last infusion was followed by complete remission and the "monster" has not returned.

Thank God she did not become addicted.

For what it is worth!!!!!
