Roommate sustained injuries
	
	
		Hello... 
I live with a friend of mine who I know has very good homeowners insurance.  I've lived her a few years and have never signed a lease, nor have I been asked.  I recently slipped and fell in the bathtub after the owner (my friend), did not clean the tub after using a form of oil scrub, and the next morning I put one foot in and slipped right back out.  I have torn many ligaments and need reconstructive surgery on my knee.  Per my surgeon, he advised me to ask her if I was covered under her Homeowner's policy even though I currently reside there, but no lease has ever been signed.
Any advice/help?  I asked her nicely to check her policy and she shrugged it off, meanwhile I'm in a brace, can't walk or drive by myself and have had crutches for over a month.  I recently started a new job and now after surgery will need approximately 2 months off, so I will not have any income.  
Thanks!
