I recently had a an accident were i fell down my roommate/friend home,i substained some serious back issued from that fall.What are some of my options

The real question here is: why did you fall?  If you fell because of something that was negligently done by the home owner, you might have a claim.  If, however, you fell because you were not paying proper attention, you would not have a claim for negligence.  (There could be a medical payments coverage on her homeowner's policy that would pay for perhaps $1000 or $2000 in medical expenses no matter who was at fault, so you may want to check into that option).  Good luck.
