If your neck is stiff, it could be caused by a minor injury, whiplash, arthritis, or another issue. Each issue is different and requires different treatment. What you can be sure of is that an orthopedist will be able to narrow down the cause of your neck pain and help you with it. Treatment could include physical therapy, posture improvement, epidural steroid injections, or even Botox! In fact, Botox injections can actually target chronically contracted muscles and reduce pain in the neck.
