I Recently Fell Hard On A Bunch Of Bricks On

I recently fell hard on a bunch of bricks on my left pelvic side I didn't feel any pain the first couple of days. After the area became very inflamed and a bulge a noticeable one came up.. I have trouble breathing, getting comfortable sleeping and walking.. It feels hot to the touch to me and I'm not sure what to do about it.. any advice would be so helpful
Thank you,
Debra.
