You may want to try techniques that promote circulation, such as aerobic exercise and a diet of whole plant foods. Avoid trans- and saturated fats. Also stress management techniques such as meditation and guided imagery lower stress and thus increase circulation to the extremities. I've seen this demonstrated. When we are under stress, blood is pulled toward the core of the body, which is not what you want for peripheral nerve health.

Personally I don't think the feather is going to help, but I don't know. I think massage of the area would be more useful, to get help with blood and lymphatic fluid circulation.
