I haven't been on here in over 2 years, but I have had CRPS for 17 years. My daughter was diagnosed with RSD in 1987; my son was diagnosed with RSD in 2000. Even though the three of us have had some of the same types of pain, we have also had some differences in our symptoms. That is one of the most perplexing things about CRPS is that it doesn't present the same symptoms in everyone it affects.
I was injured in a car accident in my right foot, and it is nearly always sensitive to the touch. The pain I experience there is a strong achy sensation. It spreads up my leg in a strong achy sensation. I do not experience the burning sensation so many people describe, but I have the edema, mottling, extreme cold temperature change.
My right arm was injured just 4 years ago in a fall. I developed CRPS symptoms almost immediately. However, it itches something fierce, has shooting, electric shock pains and "bee sting" sensations. And yes, it swells.
I hope you find a good Pain Management dr. that is knowledgeable about CRPS. This is a good place for information, also, as well as the support all of us need.
