Orthopaedist. You need to see your orthopaedic surgeon for definitive treatment.
May have more damage. You should find an orthopedic surgeon to fully evaluate your shoulder. Many things can happen after a shoulder dislocation and some of them can require surgery. Mri is often necessary to diagnose injuries and then you and your doctor can decide what is best for you. A shoulder that subluxes easily could be sustaining ongoing injury that may not fully recover.
