You : You will likely see your primary care physician to discuss your specific symptoms. Then, you will be referred to a specialist such as an orthopedic surgeon or sports medicine doctor who can help you and develop a treatment regimen for you. Be prepared to discuss your medications, the onset of the syndrome, how this is affecting your daily life, and your specific symptoms.

Go to the ER: Compartment syndrome in my opinion as a general surgeon is a surgical emergency. Seek help immediately.
