Timely question...I just wrote this on another thread a couple of days ago:
I had the test done on my left leg last August and surgery last September. Was up and running again pain-free in about 8 weeks and ran at a higher intensity and volume than I had in three years after about 3 months after the surgery. Then I started to get some issues on my right leg about a month ago, and didn't hesitate to get the test and surgery on my right. I'm fortunate to live fairly close to the US Ski team Orthopedic doctors, so I've got some confidence in their skills, and my personal doctor has a 100% success rate on fatiotomys so far over her 16-year career.
Bottom line is, I went through 3 years of mis-diagnoses before I went to the US Ski team docs, and those have been some of the most miserable years of my life. Now I've had a glimmer of hope I can get back to my old self again. The surgery is really pretty minor, and the ensuing physical therapy has helped me address a lot of other issues that I have.
Call around and find a doctor that regularly performs the surgery and is familiar with the diagnosis and procedure. My doctor never releases only one compartment regardless of the pressure test (she always releases all four), and is very aggressive with physical therapy, and gave me a few journal articles illustrating why she developed those practices. She even recently alerted me to a study (if you can call it that) that correlated running form and compartment syndrome, and noted the merit and draw-backs of the study and how it applies to my pressure tests.
Good luck and happy trails
