I'm and older woman that tripped on the mat at the entrance of the store, I was assisted up but not asked if i needed medical attention, I was not externally injured, however My body is in pain. please advise
It just sounds like an accident - nothing negligent on the store's part. I don't see a case for suing the store if that is what you had in mind. Did you see a doctor - do you have any medical bills? I still don't see where the store is responsible though for your tripping.
As an addition to my post above, it doesn't sound like you were injured externally/badly based on your post - just sore/in pain. You could have always went to a doctor (if you didn't) to be checked out.
