I would simply say this, and if you have CS you should agree, CS is unmistakable. That said there are 2 types I am aware of, CS as a result of accidents/trauma and athletically induced, mine being the later. (b) Within 30 seconds to 2 minutes of running the pressure/pain begins. Personally I get swelling/bulging in 2 of the compartments to the extent it is clearly visible to the naked eye (this never happened before the CS or when using my topical treatment). In the few instances I "power through" the pain, which I have found mostly impossible, it will lead first to numbness in my feet (though the pain never subsides in the compartments and only increases) and then I develop drop foot during the run. Within ~1 minute of ceasing the run the pain subsides. (a): I have experimented to the point that I have isolated the CS in 2 out of 4 compartments in each leg. If I don't use the treatment I always have the pain/swelling/pressure. Additionally, through experiments I know I can target one of the compartments in each leg and still have the pain/pressure/swelling in the untreated compartments. Another note, if I apply to topical treatment and don't run within ~1 hour I will develop the pain/swelling/pressure to a lesser degree, but when I go running immediately I have had runs as long as 3 hours and do not experience any symptoms. My discovery was not random luck, as I experimented with rollers, icing, heating, stretching, shoes, running surface, other topicals, etc... Having found the treatment I don't employ any other variables such as stretching, icing, or heating. It really isn't so crazy to conclude there are topical treatments the body will absorb that could change the fascia viscosity to accommodate muscle expansion. As I said, I would love the opportunity to go through clinical testing to confirm my treatment works. I am not sure how big the CS market is, but I know that after only 18 months of running I was unwilling to give it up, and surgery is not practical.
