HELP I FELL 5 CONCRETE STEPS GOING TO CLEAN WATER IN MY BASEMENT!!!?

We are renting one family house for 6 years now. The basement has sum pump because floods when rains or when snow melts. Since hurricane sandy last year, sum pump went bad and my landlord never cared to get us new one and we were flooded badly. My husband went purchased sum pump and was not professionally installed, the hoses were running from the sum pump to the little window outside so the water spells outside. We been texting my landlord for month now to come and have it installed professionally but he didn’t care. Sadly, pipes broke from where my dishwasher and kitchen sink water was going through in to basement and the water was splashing everywhere. Water also comes through the walls when rains, therefore I had to go 2 times a day swipe up the water toward the pump because the flood would cause the hot water boiler to shut off. I have been doing this since hurricane sandy very, very tiring. My landlord was notified many, many times, but he didn’t repair anything. I tried to go to get the water out (swipe it up) while my concrete narrow stairs were soaked with water and somehow I slipped and felled 5 steps down on my back. My all back was scraped from my neck to my calves plus my arms and my left palm while I was trying to hold on not to slide down, I also had a cut in my right buttock that was bleeding.. I had also injured my head, I had 2 bumps in the side, thank God I had my hair in bun other ways My head would had been slashed open. I used to have herniated and bulging L4 L5 and S1 7 years ago, neurosurgeon was going to perform surgery but my charity stopped so I never had the surgery done. I was in physical therapy for 3 months, but still had pain shutting throbbing down my leg, so I decided to go in Macedonia to get treatment, I would see my family and the treatment was very cheap. I felt better after that till now when I fall. OMG, the pain and agony I am right now from my lower back fells just like 7 years ago. My husband lifted me upstairs in the living room and gave me iboprohen. My husband had to go because his mom called him her sugar was very high and she needed him to get her meds from pharmacy, so I was left alone thinking the Ibiprophen will help little and I’ll be OK. I was wrong, the pain was unbearable, I called the ambulance and they took me to the ER trauma center. They gave me pain killers and did x-rays and said nothing is broken; I have outside head trauma, lumbar trauma and swollen wrist bone and send me home. My question is, I don’t know how to pay for my ER bill, I don’t know how to pay for my chiropractor and my MRI which still waiting for my results. If my landlord only had repaired that problem nothing would had have happened, but he didn’t care. Any opinion what I should do? My back and right leg is killing me, am in all kind meds, Percocet muscle relaxants I really don’t want to be hooked on them but the pain is excruciating. I spoke to an attorney and he said I have a case here. PLEASE ADVISE ME? Thank you.
