We have 4 production Reds, they started out as my wife's project and I quickly began enjoying them. Have enjoyed reading the posts and learning. Have my first experience with bumblefoot and read the post about the doughnut ring taped to the bottom of the foot. I tried it and after a few days could see an improvement. She immediately started walking better, and when changing the dressing I noticed the swelling on top of the foot has reduced. Apparently taking the pressure off the black spot helps. Thanks again for the informative advice and comments on the site.
