I fell from the step in the bedroom while getting into bed.  Theres a knot on the right side of my lower right leg, but the worst is whenever I put weight on my foot or try to bed my foot upward.  Theres also a terrible bruise on the ball and surrounding area of my foot.
Hello and welcome to Chat Doctor, Knot on right side of leg along with bruising on ball of foot can be seen after trauma to the foot and leg. Bruising can resolve after few days and the lump can also resolve after few days. Most of the lumps after trauma are due to collection of blood in the subcutaneous tissue. In case there is associated pain, you can take painkillers and hot fomentation. Consult your healthcare provider if lump and bruising do not resolve within few days. Thanks and take care Chat Doctor.
