Hi Terri - not sure if the PFO would be contraindication for ketamine because its an anesthetic. Also, most docs won't give it until a patient has failed other therapies. Keep up the PT, we must keep moving. Never use ice!! Consider getting a lumbar sympathetic block from a skilled pain management doctor. These are most effective when done in the first year. What is marble therapy?
I have gotten a lot of benefit from aquatic therapy, if you have access to a warm water pool I highly recommend it. And daily stretching too. Wishing you wellness ~Lottie
