Should I hire a lawyer?

So I took a fall at work in the icy parking lot while on the clock, my employer knew that the parking lot was icy for days and didn’t take any after precautions. I messed up elbow up pretty good, no fractures but bad brusing and elbow burstitus which they said is common to be a reaccuring issue. Now I know in PA my employer is protected from being sued because they carry workers comp but do I have anything since they were negligent on their part?
