Hurt on the job

[RRTtoBSN, BSN]

Two days ago, i was assisting my patient to the bathroom when they suddenly went unconscious. I was able to catch her and pull the emergency bathroom light. However, I had my 2nd back surgery in June 2019. I have been cleared for work since August on no restrictions, just if it hurts don't do it. well this hurt! The monitor tech came in and helped take some weight off and screamed for help. Finally everyone else piled in secured her for me while I took in the scene and started assessing. My adrenaline was pumping. It wasn't two hours later I felt the cramping in my back and the burning down my leg. I filed an incident report and about two more hours later, I agreed to go to the Er to get checked out. My MRI didn't show many changes since my post up MRI, except for scar tissue and inflammation. My question is.... What happens now? I have already missed one day of work. Will work file a workers comp claim or do I need to? I filed an incident report and reported it to my house administration. Can I go back to work? Should I go back to work or wait until I see my doctor and neurosurgeon? Should I look into other jobs? I am an ICU nurse, bt I am a new nurse. I graduated this past may. Idk what to do or what to expect.
