About 3 months ago, I took a step onto my left foot and felt something pop inside. There is a line of swelling on top of my foot and pain at base of 2nd and 3rd toes. Also swelling along ball of foot and inside of foot at base of arch. I have periodic tingling. The pain is dull and constant with periodic shoot, stabbing pain. My foot also gets extremely cold. I went to an ortho. Had several X-rays and a MRI. No fractures. The MRI showed some arthritic changes along with some autoimmune factors. I have been tested for RA, Lupus, etc and all bloodwork came back normal except for a Vit. D deficiency. I also am tired all of the time. I am very frustrated! Any information would be helpful!
