For The Past Aproximately 4 Months Or Longer When I

For the past aproximately 4 months or longer when i get out of bed my ancles were very stiff when I took my first couple of steps then it went away. For the last 3 weeks my feet started to tingle all the time. It don't matter if I'm walking sitting exercising, etc. It never goes away. They have tingle that much now it's like there numb. And on the bottom of my right foot it feels like im walking on something (like string or lint even in my barefeet) but there is nothing there. I dont even feel anything lumps or bumps in my foot. I can move my toes and feet no problem and For the past week even my calves feel numb. Sometimes my feet even feel cold. There are no color changes in my feet, my shoes are not to small and I do not wear high heels, usually just sneakers or slip on crocks. What could be the problem and how do I correct this.
