Dear Amy,
As per the case history and symptomatology mentioned in your post, you had disturbance in speech about 15 min post
injury, in addition to feeling sickly and mild headache.
This can be attributed to the impact as well as accumulation of fluid & blood.
Under such circumstances, it will be better to consult your Doctor.
A proper clinical+ radiological evaluation will be needed to rule out any pathological cause for symptoms.
Till that time, symptomatic relief is obtained by analgesics preparations (like
paracetamol), ice compression & adequate rest.
Maintain adequate hydration & nutrition status.
There is no need to worry, you will be fine.
Wishing you a good health.
Take care.
