Do I have a case to retry and get more money?

I try job on side 4 years ago. They told me I put security cameras together. But instead unload a truck with heavy boxes and unload boxes to second story building. Next day, I was in lot of back pain. While I try that job, I was still working at a store. I continue working at the store but lot of bending made me go on leave of absence. I stayed home but felt a lot of pain and lot of anxiety and panic attacks. I called 911 three times in one week and owner gave me eviction from my apartment. I was at the apartment for year and half. I left and went to board and care. I applied for disability and got it. I got injury attorney and got six thousand dollars. But taking back meds, had allergic reaction and had lot of chest burning and tummy burning and vomiting for a while. Ever since taking meds, I can't sleep on my left side anymore and when I lay on my back, I feel my abdominal area to be sore. I used to go to gym and play basketball but not anymore. I don't really go out much. I have been seeing a therapist. I'm having a hard time finding a job and something I'm comfortable with. When I settled the case, the lawyer said that is as best as you can get. Thanks for your time.
