I use flexall 454, but my wife says it sets her on fire. She's getting a little muscle and knee pain from the new stair stepper machine, so we're looking for something she can use that doesn't burn and won't be hard on her skin (she's real sensitive, she was a natural blonde that went natural redhead, with very fair skin), but will still ease the pain. Any suggestions? Maybe something without menthol? We're both back to working out, and if I can help her keep going it'll help me, and I need it bad, my 52" chest and 32" waist went to a 44" chest and 38" waist, I bet my body fat percentage is through the roof. I'm getting tired of getting out of breath when I bend over to tie my shoes because my fat gut keeps me from inhaling.
