Yeah, know exactly what you are taking about.
I have arthritis in both knees.
Specialist prescribed these two:
Naproxen 500mg- one tablet twice daily when needed. This has been great for me.
Ketorolac Trometh 10 mg - one tablet once daily when needed. I quit this one because I feel side effects with it (nausea, sore stomach).
Still a pain in the azz...
