Is Buzzing In Head Connected To Burning Sensation In Foot?

I have a burning feet, not really bad but I am wondering if there is any connection between my feet and the buzzing in my head. I have had buzzing in the head for over a year now and many scans on my head and neck have shown nothing. The buzzing is not in my ears but up the back of my head to the front. I have tried acupuncture, massage , been to a chiropractor, Tried Gluten Free food, Everything but to no avail. The burning feet comes and goes and at the moment is not too bad. As I say I am wondering if there is any connection?. I am 74 years old but am very active, my husband and I teach Martial Arts including weaponry and Tai Chi/Chi Gung , we also swim 4 times a week, summer and winter, and I also use the Treadmill [for 25min] at the gym on the days we are not swimming, have you any suggestions ????
