You can always just go see the doc, find out what the options are that won't interfere with your tendon healing properly and go from there. That way if you decide you want to go ahead with a treatment you have someone on board with you. I have not heard of a contraindication between ketamine and soft tissue healing/remodeling. That is something I should look at. Again there are multiple protocols. I am only treated for an hour, no restrictions after except no driving for 24 hours. I am allowed full range of motion.

There should also be several options besides ketamine available that wouldn't cause a problem with your surgery or PT. Being more comfortable may actually help the overall situation and allow you to rehab even better.

Hang in there!
