Thanks for the response daniella. My wife, several years ago came to the conclusion not to allow any invasive procedures be performed on her to treat her RSD. Even blocks are temporary and may make things worse or may not but not willing to risk it. She looked into pumps and spinal stimulators and stated that she'd only consider it if things became very bad in the future. She did allow for ketamine and lidocaine infusions with weekly ketamine booster shots but did nothing for her and in fact her right leg and ankles have swollen since then. This was a 4 day out patient treatment. A 10 day treatment may work but GW hospital does not provide that. Earlier in her disease we went to Johns Hopkins which turned out to be a bad experience. She does have a pain specialist that does a very good job in controlling her pain. My wife is very vocal with doctors in what they may demand of her and will tell them she does not agree with invasive procedures and meds that make her sick, gain large amounts of weight and those that make her head fuzzy such as anti-seizure drugs. She takes pain meds, muscle and bone meds, anti-inflammatories. She diets, eating plenty of fruits and veggies and exercises.
