Tonight, a big bottle (5 liter) dropped from my sisters hand (age 14) suddenly. it severely damaged her toe nail, breaking it in half and causing moderate bleeding. When we were covering her nail area with a piece of cloth as first aid, my sister told me that she was not feeling good, her head feels weird, she can not see us clearly etc. then she suddenly felt unconscious. My parents sprayed some water on her face and I made my sister drink some water. Even though she regained consciousness, she was feeling dizzy and constantly telling that her head hurts, she can not see clearly etc. now my parents have taken her to emergency at the time of writing. Can anyone help me by providing me with medications, suggestions and more?

Thanks,
Shahed Amin.
