Hi, so I was praying on my knees, while sitting on my feet and leaning forward for about 30 mins. I got up and could not put pressure on my foot. The next day there was swelling and what looks like a huge blue bruise on my foot, and I have to limp to walk. At first I couldn't put any pressure on it at all, but today I can even though it looks like the "bruise" is starting to spread a little. Is this a huge concern? It only hurts when I walk on it, not when I am just sitting.
