Looking for Fibromyalgia Pain Relief

Anyone know any OTC or herbal treatments for fibro pain? my neck and back are just so stiff and tight. stretching doesn't work, and I move around all day at work. I've tried all kinds of meds. Advil, Aleve, aspirin, Tylenol, backaid. My doctor's only advice was to try acupuncture. But the earliest I can call is Monday, and who knows how soon I can get an appointment. I just hate being in pain until then. I'm not a huge fan of icy hot smelly stuff but if it works I'd try it. I just don't want to add more burning to the pain that's already burning and tingling. I just feel hopeless because idk what to do. heat/ice is a hit or miss too. sometimes helps or sometimes worsens it. Really thinking of trying weed but my pristiq can't be mixed with it😭
