Thanks! I got all 8 tested and my highest was 45. That was the simplest one, it was a little below 10 before so that's an obvious spike. Several were around 20 before exercise (above 15 is diagnosed as compartment syndrome) but then they were basically the same afterward. Doctor who did the test diagnosed CS in 7 compartments but then the surgeon was unsure about the diagnosis.
I'm thinking I'll have surgery in May. Thanks for the response, I'm glad it helped you!
