No, it's not bound to get worse. You must find the things that help and identify the things that make it worse and try to eliminate them. You'll almost certainly need pain meds and other meds to target specific symptoms. Most people with RSD will eventually have an effect on how they think which frequently manifests as depression. There are meds for this as well if and when it occurs. You'll probably get little relief from pain meds but some of us get some relief from one or another. Eat well, sleep well, and get as much exercise as you can tolerate but try to never over do it. Avoid caffeine, try grape seed extract and ginko biloba. Listen to the docs and therapists but never take their word as gospel because each of us reacts differently to stimuli, medications, and exercise.

It's very important to keep fighting even if we can't beat it. The disease may change your life but there is still life after RSD. Try not to let go of things unless there's no choice.

Best wishes and good luck.
