I have eye witnesses. I had been completely incapacitated by plantar fasciitis and could barely hobble into twice- weekly PT. Massage, ice, ultrasound and home exercise. I would even get hystamine stings from the treatment and cry out. Nothing helped until I got an RX for flexeril. One evening in desperation I doubled the dose and the next morning I could bear weight. Didn’t make the connection until I repeated a few weeks later. I convinced the dr to increase the dose and I was able to discontinue the PT. However, really try to get off as soon as you can. Flexeril or cyclobenzaprine is a muscle relaxant.
