You can always reach out to ask questions before you book anything. Personally, on my online booking system, I have a place where clients can leave notes if there is something specific they are looking for. I also have all my contact information available. You can reach out to see what kind of training they have and explain what the issue is to see if they think they'd be able to help. A Rolfer will definitely know this protocol; if you can't find a Rolfer specifically, Structural Integration is similar. Your issue definitely sounds like a more specific strain that not all massage therapists will be able to work with, so reach out and ask ahead of time, and if the first one doesn't work out, don't get discouraged, you can always try somebody else. Sometimes it takes a couple of rounds of trial and error to find the right fit!
