Look up the Bowen Technique. I successfully used this to eliminate serious swelling. Basically using a specific washing soda crystal wrapped in a cotton cloth and tied around the swollen area overnight I was able to wick off excess fluid. It shocked me that it worked. I believe that prolonged swelling interferes with the lymph system, so by removing the excess fluid the lymph system can get back to doing its job.

I watched a YouTube video demonstrating the technique and purchased the crystals from Amazon.

Ice exacerbated my CRPS symptoms. Anti-inflammatories damaged my stomach. This crystal technique. non-invasive with no down side. Acupuncture helped minimally.

What helped me the most was the combination of LDN and pool therapy.
