Hi thanks for your question.
Chest bruise and fracture
ribs do produce chest pain
.SIince movements of respiration moves the fractured rib so it gives pain.Ruptured spleen
is surgical emergency ,it woun't wait for days to produce pain.There is no harm in reconsulting your Doctor.
You need analgesic
anti inflammatory drugs(pain killer) for relief of pain
Hope this answers your question.
