FAQ Frequently Asked Questions

Stiff shoulders are caused by muscle tension in the neck, shoulders, and back. Maintaining a forward-leaning posture for long periods, working at a computer with your arms raised, or having a habit of shifting your weight to one side while standing are all factors that put strain on the shoulder area. Since the nature of the pain varies from person to person, it is important to identify the cause if symptoms persist.

At YAYOI CLINIC, we offer “shoulder Botox”—injections of botulinum toxin—to treat stiff shoulders caused by muscle tension. This treatment aims to relieve excessive muscle tension. A physician will examine the areas of stiffness in your shoulders, muscle development, and any asymmetry between the left and right sides to determine your eligibility for the procedure, as well as the injection sites and dosage.
