Help! Lethargic,pain,nausea,numbness… of appetite what is this?

Ok. About 2 months ago I hurt my back working in my yard. So bad that I thought I was paralyzed the next day because I could not move at all. I ended up going to the ER and they suggested a MRI. Well, I couldn't afford that. So I just dealt with it and now I can get around fine but I have a constant numbness and tingling in my fingers of my left hand. Then last week I think I moved wrong or twisted a neck muscle. It was a shooting pain followed by a sort of black out and dizziness. Since then I have felt increased neck and back pain, nausea, decreased appetite, numbness in my right hand that comes and goes (worse at night) along with the numbness I already had in my left hand, joint and muscle pain and severe lethargy. I know this is a lot but and any help would be great on figuring out what is going on here.
