I was having major pain in my knees, ankles and feet. I saw specialists, had therapy and took meds. Finally, a chiropractor worked on my back and all the pain went. Amazing. I used to wake up in the morning and walk around on tip toe because it was too painful to put my foot flat on the floor. 40 years of three inch heels does a job on your posture. Now I wear flats, sneakers, and one inch dress sandals. Life is too short to spend it in needless discomfort.
