As far as a relapse goes, if you took your pills due to a legitimate medical reason, and you did not abuse them, and took them only as long as necessary, then no, it is not a relapse. When I had my
broken leg surgery, I did not feel like I had relapsed. But, I did start counting my clean time after I stopped taking pain pills. It's really kind of an individual thing, and everyone has their own feelings about it.
You are doing great. Keep moving forward! I wish you all the best.
