If there is tinkling with touch it seems that would be due to contusion. If the head injury is serious there can be a tinkling sensation due to a head and neck injury...symptoms of a concussion can be subtle and may not be immediately apparent. Symptoms and that includes a headache can last for days, weeks or even longer.
You may want to see a doctor depending on the severity of a blow to the head that can cause a blood clot.

Whit a head injury is always smart to see a doctor. Hope it is nothing, but I would stop at the local hospital emergency. Better to be safe.
