Hi, By Federal law people with RSD automatically can receive SSI/SDI benefits. I've had RSD for about 7 years, and it took 2 years to get benefits, but I also got back payments, and a lot of cash. Please check into this. I'm positive it will work for you. I too spend many days in bed and couching it. It helps to elevate my legs with a heating pad and Lidoderm patches. I also take several pain meds.
Sympathetic and empathetic,
Sylvia
