I have noticed that the top of my right foot is becoming numb after sewing for a while. No pain (yet). Any suggestions? I have put the presser foot on the table and I am using my right hand, but this isn't easy or speedy when I have to chain pieces through. I have a start/stop button as well, but, a pain when chain sewing.
This is a pretty recent problem. I usually sew barefoot, maybe wearing sturdy shoes?
