Caller identified herself as from Orthomedic Medical...or something similar. Asked me if I had back and knee pain...which I do and asked me if I was on Medicare...how tall I was and if I lived at my address (she had the correct address). I told her that I was not interested in getting a brace out of the blue...that first I'd have to see a doctor about it. She said that they would call my doctor first. I suspect a scam and I told her that I was not interested. coincidentally I asked my chiropractor last week that I wanted to get a medical opinion about my condition...why am I having repeated back pain? I did report that at the last visit I felt a knee pain at the time of the adjustment.
