Years ago, before I was diagnosed, I had some bad swelling of my left ankle. I also had a lot of varicosity in that leg - much more than my right, and I still have problems with circulation. So I get a lot of purplish-greenish mottling in that leg and ankle that looks worse when I exercise or take a shower.

However, I haven't found anything I can point my finger to and say "This is MS." A lot of people have circulation problems without having MS... Still, it's weird. My right ankle and leg are fine - it's just the left.
