I Recently Fell, Due To Moving And Having Many Boxes

I recently fell, due to moving and having many boxes around apartment, I tripped into a large box and really hurt the back upper portion of my leg. since then there has been a growing bruise...the middle of the bruise is a kinda dark pink and the surrounding area is very dark grey or black. it hurts in the middle area that is the kinda orange color, I can feel a long lump and when I push it it really hurts. I am on numerous medications due to rheumatoid arthritis, fibromyaliga, bad spine, high bood pressure, high cholestrol, very overweight at 5'3" 198lbs (due to steriods and not going outside much). since I feel maybe 5 days or so ago I wasn't sure if I should worry about it because usuaally bruises get purple, yellow etc. and this is weird. I do take morphine and hydrocodine for all of the pain I have in my entire body. can you help me ? thank you very very much ! karen
