Talk to doctors trained in the 80's and 90's, they will tell you they were trained to make the patient as pain-free as possible. Thus, their training focused on alleviating symptoms, which included using pain killers. Many have been on tv talking about this 'school of thought' and how this/they inadvertently enabled the opioid crisis that is continuing today. They were told by the pill manufacturers that the synthetic pain killers were 'non-addictive' and so the doctors 'handed them out like candy', according to one interview I saw.
