I am interested in seeing how many families there are out there that have 2 or more family members diagnosed with CRPS. I have a brother diagnosed a decade ago with CRPS and last year I was diagnosed with it myself. We both had injuries on the right leg (foot, ankle, toes) and both have CRPS on that limb on that side of our body. There are many symptoms that are the same and just as many that are different. I cannot help but wonder that families affected by multiple cases of CRPS would be a great place to do research. I was wondering if anyone knows of any studies done on this subject? Also I would love to hear of any other families that are struggling with this in multiple family members.
