4 days ago I pulled my calf muscle very badly. I could not flex my foot or apply much pressure. I have been icing it, propping it on pillows and have but an ace bandage on it. Today I was able to walk and move without much pain though I was slow and careful. This evening my leg is swollen, bruised and warm to the touch. I have iced it again and placed the bandage back on. Should I be worried?
