Hi, i dont want to overreact to this, but it's a bit strange. I have transient episodes of numbness and strange tingling in my feet and have figured this would just go away, but now i have a small area on my ankle that is completely numb with rough skin over it. Also i have a lot of pain on the bottom of my heel on one foot--this is chronic and has been a problem for months, despite trying everything to alleviate it. Are these symptoms something to be concerned abou?
