Two days late, but I had never heard of "tramadol"

Looked it up.. https://www.health.harvard.edu/blog/is-tramadol-a-risky-pain-medication-2019061416844

Seems it's in class by itself. I have had Hydrocodone, Codine, and once, for a bad kidney stone, they gave me Dilaudid in an IV... wow! Instant relief.
Fortunately, I have VERY few allergies to any drugs and tolerate standard doses as if they were designed for me. I am also not an addictive person... to alcohol or pain meds. I am perhaps over-cautious in how much I use of either, but I'd like to keep my status.
Just lucky, I guess...
