Hi Maralyn,
I am glad you found us and are able to ask any question that you have..there are so many knowledgable people on this board, who share their experience willingly and with kindness. I am sorry you are experiencing so much pain that it is difficult to walk, and having to work.

I have RSD/CRPS in my lower limbs and I relate to not being able to walk as the pain my left foot and lower limb is severe.

My lower limbs are swollen with edema and I have discoloration as well, along with burning pain..I had a left ankle foot injury in 2006 and surgery in 2008..
I'm feeling a lot of pain in my back, hips and shoulder..not sure whats going on there yet..

People have been diagnosed by a variety of practitioners..some by their own General M.D., by physcial therapists, orthopedic surgeons, neurologists, or a Pain Management specialist who is also an anasthesiologist. A good pain management specialist, who has vast experience with RSD/CRPS would be a good specialist to help you with a diagnosis.

After diagnosis, treatments vary..some administer sympathetic lumbar blocks early on, along with meds such as Neurontin, or Lyrica along with Cymbalta.

Everyone responds to treatment and medication differently so it depends on what works for you.. It is best to begin treatment as soon as a diagnosis is made.. Refrain from using ice on your injury site, as if it is RSD, this can worsen symptoms.
I hope your symptoms are not from RSD, but you have come to a great place for imformation and support.
Keep us posted!
