Below is a link to a legal guide I have written about Slip and Fall accidents and premises liability claims in California.
It's impossible to give you a dollar amount for your injuries. However, it sounds like you may have a case. I'm licensed in Illinois, but the basics are the same. You have to prove that the grocery store was negligent (if they knew there was a spill and didn't clean it up, for example) and that their negligence caused your injuries. Then you need to prove damages, which would include the medical bills and lost income that you mention. Make sure you continue to get the medical treatment that you need, and contact a personal injury attorney in your area. If you'd like a referral, I know an experienced personal injury attorney near you. Feel free to contact me. 1-800-807-9530.
Whether you should be compensated at all is the threshold issue. You must first establish liability against the store. You did not specify what caused you to slip and fall. You must prove there was a dangerous condition and that the store either created the condition or had sufficient notice of the condition and did not correct it. These are difficult cases and trying to evaluate damages on the basis of the facts you provided is impossible.
You should see a lawyer right away and not attempt to deal with this yourself. Good luck.
