Can I sue for negligence or long term health issues?

I was stuck by a dirty HIV HEP C needle left by another employee. The manuals for protocol were 5 years out of date so the facility was unsure of what to do or the meds to give. I was therefore sent home with the wrong meds and told to follow with employee health. When I went there they 2 gave me the wrong things based on manuals and being unable to write scripts. I therefore called the CDC myself and banged on DRs doors until I got myself help. I unfortunately have had nothing but trouble since. I ended up in the hospital with pneumonia during the antiviral cycle because I was told I had to keep working and they took all my PTO when I got pneumonia. They have since rectified that after a board meeting where they found 64 errors that happened to me, such as wrong meds and no follow ups except for the ones I made. I was never given a therapists name, which was apparently supposed to happen before I returned to work. I now see a cardiologist because the antiviral have caused a problem in my heart with one of the valves, or as work wants to say "it may have". But I am 26 and never took so much as a vitamin before all of this. Will my workers comp continue forever or is this something will eventually say comes out of my pocket? Oh and now the needle bins have been lowered, manuals updated, meds stored in pharmacy and scripts updated in employee health.
