Getting restful sleep is one of THE most important things in handling chronic pain.
A very high percentage of people with CRPS will struggle with getting a good night of sleep.
Besides the typical things they recommend for getting a good nights rest, (Google them) a lot of us ending up using a medication.
Trazodone has helped me greatly as without a good night of sleep, handling the next days pain becomes
just that much harder.
As they say in the financial industry...."Your results may vary"!!
One thing with CRPS is a certainty. A medication that works for one may or may NOT work for another! Experiment until you find something.
