I don't know if this will help,nor have we personally been there,but were once referred to the Pain Center at Cleveland Clinic to see the head of the team,Dr. Stanton-Hicks,by my daughters treating doc in Chicago to confirm her RSD dx. Stanton-Hicks has written articles in pain management medical books in sections pertaining to RSD,mostly in re to block techniques. I do believe you would be able to get your dx there,but am adding a caution here. We were seeing Dr. Lubenow,medical director at Rush Pain Center in Chicago and Stanton-Hicks was his mentor. Rush is VERY spinal cord stimulator oriented [SCS],meaning that after some blocks and meds didn't cause immediate results,the SCS is pushed on every visit. You can say no,but it will be pushed hard. Back then it was a 9hr drive for us and too much for my child to withstand. Your other option would be to seek some valid local support groups in Ohio and get some patient opinions. I would also try the RSDSA website for ideas on seeking local support groups in Ohio.
Finally,don't lose hope! It took 3yrs of pursuit to get a dx and 3 more pain docs to find the right treatment. By then it was in both her legs,yet she was able to achieve 100% remission with conservative treatments,and pain relief enough to do intense PT . Hope this isn't too late to help
