My weight came down hard on the left side of my foot as my foot slid in my untied shoe. There is no bruising but some swelling and a hemotomo type lump (that is hard and does not move) on the bottom of to the left of the arch. I have been icing it an cannot put my weight on it without pain. I can touch the top of the foot and even rub gently around the lump, but it is painful even though not excruciating. Should I go to emergency room?
You should first do an x-ray to rule out whether the lump is from bone or from soft tissue further workup will be accordingly
