The bump could be a soft tissue swelling due to the hit. This can remain painful for a few days and cause headaches too. If you develop persistent nausea, vomiting, excess sleep, severe headache, difficulty in walking and balance, tremors, seizures, vision problems, ringing in ears etc then consult a doctor immediately. These symptoms develop if there is a brain injury or bleed. Take care!
