Hi, I have just in the past 1 1/2 years been told I have RSD. I injured my knee at work 5 years ago and had to have 2 surgerys on it. After the second surgery is when I developed RSD.  Now that the weather is getting colder here in Ohio the pain in my leg is getting worse.( the RSD has spread from just around my knee to my foot and hip)  I have been waking up the last few nights after only geting about 4 1/2 to 5 hrs of sleep because of the pain.  The pain during the day has increased as well. It is getting to the point were it hurts to much to drive. I am taking a sleeping pill at night, it puts me to sleep but it isn't doing a very good j ob of keeping me asleep. If anyone has any suggestions on how to get back to sleep once I have woken up please let me know. Thanks
