Suggest Treatment For Severe Leg Pain Caused By An Injury

Last Monday in a wind storm with no power I fell down some stairs. About 12 hours later my left leg was very bruised with a knot the size of a softball on it just to the right of my shin bone in the middle of the shin. It was also every red for about four inches under the bruise. (History, 44 yrs old female, hbp, copd) I when to the ER and the doc told me it badly brusied. I have practiced R.I.C.E for a week. Now the ankle is also swollen and bad bruised and my foot of about 3 times the size of the other one. I was give Hydrocodone APAP 5mg/500mg tabs. I get a sharp pain in the leg where the knot is and travels both up and down the leg. Here is my question. Is they anything i can be doing at home? I do not want to go to the doctor for him to tell me I just need to give it more time to heal. I do want to sound like a cry baby but it really really hurts. And it looks 4 times worse then a week ago. Also it is every painful to walk on it.
