When I went for physical therapy after an auto accident, I told the PT that I was on narcotic pain relievers (Vicodin) for a few weeks, but that I didn’t take any for about 5 days prior to my appointment because I was feeling better. He then told me I was feeling better due to the fact that I still had the medication in my system even after 5 days, and that studies have shown that people have had the narcotic pain meds in their system even after a week. Now, I know that the pain relievers aren’t having any therapeutic effect after 8-12 hours at the most, but I was wondering if this PT really knew better, and he was just trying to BS me so that I’ll sign up for a lot of sessions, or do they really believe this.
