@salvatore Hello, you can take Anti-inflammatory medication, remedies like a cold compress, heat therapy, pain medications, and exercises and stretches. The heat helps to relax tense muscles and soothe a stiff shoulder and a cold compress can help reduce swelling in the shoulder. Exercises like Shoulder raises, Shoulder rolls, Chin retraction, and Cross arm stretch may help you. Eating a healthy, balanced diet along with medication and exercise will be helpful. Please consult your doctor before trying any of these exercises. Thank You.
