Query: Mom developed injury due to tension knob

Got this seat in May, and by June I had bad wrist pain from the tension knob. In November I realized its from twisting the tension knob multiple times daily! I replaced the seat with the Cosco Alpha Omega (love this seat, no knob!)I saw an orthopedic physician & he said its De Quervain's disease. Yesterday I finally got a cortisone shot, as it got so bad I can't move my thumb, lift my baby without pain, or open a jar.And I'm a fitness instructor, so its not like I'm some weak whiner with fragile joints or anything!This seat was otherwise a great buy, and I put it in my husband's car, since he rarely uses it, but if you start to get achy wrists---exchange it! The only cure for De Quervain's is to stop the motion altogher. (mine went on for months before I figured it out, so if the cortisone shot doesn't work, I'll have to have surgery)I will be calling evenflo.
