Fall from 6ft height is a type of injury
where you can have severe trauma.
You have described your injury well.
Yet few questions are unanswered.
Was there any nausea/vomiting/unconsciousness
Do you have moderate/severe pain
Probably the answers are ‘no’.
If so then you need not to worry.
You can take analgesics & anti-inflammatory.
Usually pain, parasthesia may persist over a traumatised area.
But hearing your mode of injury and a large swelling over there, you should consult a doctor.
Hope this help.
