I so appreciate your suggestions. I have exhausted all these avenues but with a minimum of improvement. The problem is with the first joint closest to the nail. It has very little flex ability and wearing the braces is even more restrictive. I have made an elastic loop that goes around the bow stick and my middle finger. That is to ensure I do not drop the bow. I am playing through the pain but the issue is bow control. It tends to slide and you know what a horrible screech can result. I am working on bow exercises to help prevent that. I have been checking your bow technique videos. All of your suggestions are very useful. Perhaps this conversation will be helpful for others. I wish you all the best on your surgery Casey. Thanks again for your responses.
