hello. Welcome to HCM.
The only concern will be presence of a hairline fracture
which is common with such a fall. You can get an X-ray as a preliminary step. Also, in also, there is bruising or pain in left upper abdomen, you have to get a USG,. Most things depend on the severity and impact of fall. It is always better to consult an expert to do that judgement for you. So according to me, better visit a doctor.
