I am 53 year old female about 137 pounds who used to stand on my feet for extreme amount of times. I live with hard wood flooring throughout the entire house. Approximately the last 2 years the bottoms of my feet have become very sore and stiff especially after sitting or sleeping or not using them to walk on for a period of time, to where I walk like a much older person until I take more and more steps to walking normal, but it is chronic now which I live with everyday. I cannot wear high heals any longer or soles that have no cushion. But the main question has to do with the top of one foot as it will make the noise of a crack each time in mid to ending my step from a walking motion, in other words as the large toe is in a flexed position. I believe the area of concern is the Navicular bone area. It can also be sore to press around the area. There are times when it does not always crack but I still have the other symptoms. Can you please give me an idea of what this could mean. I am not a diabetic and I eat very healthy whole organic foods. Thank you.
