Sorry to hear about the range of motion trouble. I feared that was the case. Bone stimulators are helpful. My mother had one for a major spinal surgery. I wouldnt give up on the pool as it might be one your best resources for movement. I found even swishing around in there with a buoyancy belt helpful for swelling and circulation. I know it is hard getting back and forth. Could you check YMCAs, gyms, community centers or even sometimes assisted living/retirement communites for one with kind of quiet hours off-time that you could go? Often they will allow a pay per visit situation. Especially if you are on crutches.

If you are burning through PT hours without much gain on land they could maybe order aqua therapy at a nearby center or hospital pool.

Be sure to check out Dr. Pradeep Chopra's video on youtube "CRPS Diagnosis and Management" for two hours of tips and treatemnts from a rational, well regarded specialist.

I hope you find relief soon!
