Hi there ~
I understand your concerns. I believe you fainted and hurt your head, but do not mention whether there was loss of consciousness
associated with it. Pain on touch is not uncommon in such situations and feeling dizzy and ringing in the ears are common initially after such a fall with hurting your head. They should go away in a few days. If they do not and you are continuing to have worse symptoms you might benefit from a CT scan
or an MRI
of the brain. I hope you visit with a doctor who can run these labs and imaging tests and give you the right diagnosis.
I hope this helps. Take care and have a lovely day!
