Guys. I have had a left swollen ankle since Friday night... it hasn't gone down at all.. it's now very itchy and I'm starting to get little red blotchy bumps on the top of my foot going up my leg... should I get concerned. Or call doctor tomorrow ? I did ice packs most of the day yesterday and elevated it for hours.. didn't seem to take any swelling down..
