I have been jobless and without health insurance for 1 year. 3 days ago I found a job and i went from hardly ever walking to walking all over and all sorts of sitting, standing and new shoes. After 3 days of alot of activity I noticed my lower leg (mid calf) to my ankle and part of my feet were a bit swollen. I am a bit scared as I still need to wait 3 months to get health insurance from my new job. Could it be the shoes I was wearing? I put on 2" inch heels for the 1st 2 days and my back was killing me, so I bought lower "kitty" heels. I am 58 yrs old.
