Hi Swannie,
Welcome to the Pain Mangement Forum. I am glad you found us.

With that said you need to look at the cause of your edema before you can determine if it cause be "cured." Edema is not a specific medical condition. It is a symptom of a condition.
So what causes your edema? If the cause can be "cured" than the edema can be "cured." Think of it this way. When you sprain your ankle it often results in edema. As the sprain heals the edema resolves...or is "cured."
I hope my explanation makes sense. You didn't provide very much information. If you would like to add to your post please feel free to do so. We may have better suggestions for you.
Best of luck to you. I hope you will feel free to post more detail and to be active in our community. I will look forward to hearing from you.
Take Care,
