I’m worried about going back to work.

If you go back to work, great! The most important issue is your health. If your medical expert opines that you can return to work, than I would suggest you try. If you successfully return to work for the same wages, then the case becomes a “closed period” for the time you missed work for the injury. If you returns to work at limited duty and makes less wages, you could be entitle to partial compensation based on the actual wages earned.
