It is definitely not too late to seek legal help. In fact, I would say the most important thing for you to do right now is to continue to follow the advice of your doctors and get yourself healed up. However, it would be too soon to try to negotiate with an insurance company to settle your case because right now it sounds like you don't really know the extent of your injuries. If the establishment where you fell was negligent, then they would be responsible for your injuries, unless your negligence exceeded theirs. Certainly, your time off work would be an element of your damages, and that could continue to increase until your injuries heal. It may be that the location where you fell has what is called Medical Payments Coverage. Typically, this insurance coverage is available irrespective of whether you were at fault or not, and this could be used to pay for your medical expenses. Usually, the limits on med pay coverage are fairly low, but still, it can help to offset some of your medical treatment costs.

I would strongly encourage you to seek out an attorney to at least discuss your legal rights. I practice with the Indianapolis personal injury law firm of Goodin Abernathy, LLP, and I would be more than happy to answer any questions you might have.
