You have sustained a soft tissue injury (sprain) to your shoulder. You may experience some bruising in the upper arm. This normally takes 6 weeks to heal, but soft tissue injuries can persist for up to 3 months. You may use the arm in the meantime and indeed it is important to keep the shoulder moving to prevent stiffness but not to aggravate it. Use the sling (if provided) for comfort only, and try to wean out of this as soon as possible.
