I would like to present a temporary solution to the stinging pain that patient experience. The application of Hot/Cold surface to the aching joints seems to be helping for the pain. I tried to keep in mind to give a certain liberty to the patient, trying to move a bit through the pain.
I fabricated pouches filled with barley grains. Those pouches can be heated up in a microwave or cooled down in a freezer. Then these pouches are applied to the body on the aching joints, switching every 15 minutes from hot to cold and then hot again.
