The problem started several months ago. It was at a mild level. It started after I was using some headphones with YouTube videos. Since then I have learned that there is a correlation between the problem and headphones.
What took care of the problem was reflexology. Press hard all along the area of the foot where the foot pad meets the stems of the last two toes on the foot. Rub back-and-forth and finger walk along that area for at least a minute.
If the problem starts up again, just repeat the procedure and then an hour or two it will be gone. you may have to do this every day. Of course to both feet.
