Tibialis anterior is a large muscle which pulls your foot up.
Compartment syndrome is caused by the sheath around this muscle becoming too tight for the bulk of the muscle itself. It can be treated by manual techniques to loosen the sheath. Further, bio-mechanical work for the running action is essential. Without proper care this can be a difficult condition to treat and give long term issues. Get it seen to!
Other issues around here are straight forward muscle strains, issues with the nerve from the back of the knee and the lower back.
