I have used Diclofenac gel a well and it doesn't seem to help that much and I probably have used more at a time than I should. It's mostly muscular. I have not tried the CBD ointment but I know that and the pills are expensive but I have heard good things. Ben Gay helps for a few hours and wish I could have that feeling all day lol.....I'm so tired of paying for stretching, bike riding etc...You would think by now that my muscles around the knee would be strong but they just aren't getting there.
