Have you tried a knee brace, or the newly available over the counter rub

i have three different types of knee braces and they don’t help a ton. i have my medical marijuana card so i’ve tried cbd/thc salves which i’ve found to be a little more helpful but still not great. other OTC topicals like asperceme or lidocaine just numb the skin instead of treating the joint pain. i get synvisc injections every 6 months since that’s what my insurance allows, but i need something to hold me over in between shots for day to day pain
