Hello dear and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
I'm sorry for your mother's accident.
Head trauma is a common concern in elderly.
You should not be worried about the lump, it is as normal as it can be.
Scalp have a high blood supply, and injury to these areas often results in bruising or swelling.
In your mother case the injury seems mild, so there is no need to call 911.
If she develops other symptoms such as:
bleeding or clear fluid from the mouth, nose or ear.
pupils of unequal size.
you should call 911 for further evaluation.
Meanwhile, I recommend using anti-inflammatory medication in case of pain such as Ibuprofen 400 mg three times a day.
I also recommend using cold compresses at the area to reduce the swelling.
Hope I have answered your query. Let me know if I can assist you further.
