Has your condition been diagnosed by a consultant? Have you tried physiotherapy? I have had good success with acupuncture in the treatment on compartment syndrome as this can help release the fascia and alongside exercises which can help address any muscle imbalances which may cause you to over compensate with a particularly muscle group (ie your flexor hallucis longus). Chronic compartment syndrome tends to be a self limiting condition but the best person to ask is the person who diagnosed your condition as they have your full history and have seen your lower limb alignment.

Hope this has helped!
