I suppose you got the relevant investigations done at that time.
In case you have not yet got them done I suggest you get the following investigations done at the earliest:
1. Non contrast CT scan Brain ( To rule any basilar skull fracture
or underlying head injury
2. X- Ray chest ( To rule out any rib fracture
1. Since you had a cut I suppose you have taken an Injection Tetanus Toxoid
at that time.
2.Medications would consist of oral antibiotics
( because of the open injury), non steroidal anti-inflammatory agents tablets and a local antiseptic ointment over the cut.
3. Rest for the rib injury.
