Do I have a personal injury case if my current doctor's treatment is not working on me?

I am on dialysis and I was given these 2 drugs that are now into cause hearing loss in patients. Especially if they'd have damaged kidneys and impaired hearing. I had both. I had a kidney/pancreas transplant both lost those earlier this year because I was sick. So what kidney function I had was like 5 percent. My hearing was also compromised I was deaf in my right ear since 2003 so I only had what was left in my left ear. I wore a hearing aid. I was given gentomycin and vancomycin. Together they will damage the inner hairs of the ear. I woke up on May 16th and I couldn't hear a thing. My walking is also messed up, everything goes up and down. Doesn't bother me when I sit. Anyway, someone was negligent, some should have checked. My regular doctor doesn't cover the dialysis clinic; there are 2 other doctors there. I found out I wasn’t just given this once but at least twice. It was obvious my kidneys weren’t working, and they knew I wore a hearing aid and that I was deaf in my right ear already. Why would they do this knowing I only had my one ear?
