I have a left swollen foot and ankle everyday for several years....when I get up in the morning it's okay but after 20 minutes or so it swells and it is only my left foot....sometimes my left leg will turn blue from my knee down and sometimes my feet look blue. My joints in my fingers are getting knotty and are painful with weather changes. My right shin has also been very achy right on the bone. I feel like it's all related somehow but my doctor is of no help. Twenty-seven years ago I suddenly developed knots all over both shins that were very painful...I was pregnant with my 3rd child and I was sent to a specialist it was thought at the time that I may have had Lupus but 6 months after my son was born the knots went away. What could be going on in my body?
