Health professionals use the Pain scales for assessment during hospital visit

 
Health professionals use the Pain scales for assessment during hospital visit, out-patient/in-patient procedures etc. Patients typically self-reports their pain using a specially designed scale from 0 to 10 to indicate pain level. Health experts use the pain scale to better identify/recognize certain aspects of the patient pain-level, including pain duration, severity, and type. Do you think this is the best way of assessing pain severity? Why, or why not?
