SymptomsBy Mayo Clinic staff
The pain and other symptoms associated with chronic exertional compartment syndrome may be characterized by:
- Aching, burning or cramping pain in the affected limb — usually the lower leg
- Tightness in the affected limb
- Numbness or tingling in the affected limb
- Weakness of the affected limb
- Foot drop, in severe cases, if nerves in your legs are affected
- Occasionally, swelling or bulging as a result of a muscle hernia
Pain due to chronic exertional compartment syndrome typically follows this pattern:
- Begins soon after you start exercising the affected limb
- Progressively worsens as long as you exercise
- Stops within 30 minutes after the affected limb comes to rest
- Over time, may begin to persist longer after exercise, possibly lingering for a day or two
Taking a complete break from exercise or performing only low-impact activity may relieve your symptoms, but usually only temporarily. Once you take up running again, for instance, those familiar symptoms usually come back.
When to see a doctor
If you experience unusual pain, swelling, weakness, loss of sensation, or soreness related to exercise or sports activities, talk to your doctor immediately, because these symptoms may be associated with conditions that require emergency medical treatment. Don't try to exercise through the pain, as that may lead to permanent muscle or nerve damage — and jeopardize continued participation in your favorite sports.
Sometimes chronic exertional compartment syndrome is mistaken for shin splints, a more common cause of leg pain in young people who do lots of vigorous weight-bearing activity, such as running. If you think you have shin splints but they don't get better with self-care, talk to your doctor.
