My 78 year old mum fell backwards on Christmas eve bumping her head on the tarmac driveway. She has vascular dementia and was on antibiotics for a UTI which was causing additional confusion. Therefore, she didn t display any change in normal behaviour after the fall. A golf ball sized lump appeared almost immediately which turned to a bruised lump over the next 24 hours. The bruising has now spread right down into her neck and the lump is still there over a week later. Should I be seeking a medical opinion on this or is this normal? She is also quite bruised on her side and occasionally complains about that too.
