Be seen today
Arrange a routine or prompt medical review for new bruising, increasing tiredness, bone pain, falls, changes in walking, new learning difficulties, or possible seizure activity.
Coughing or choking with food and drink also needs assessment because it may signal a swallowing problem.
Seek urgent medical help for:
A first seizure or a clear change in a known seizure pattern
Bleeding that does not stop with firm pressure
Sudden severe bone or joint pain
Repeated choking, fever after aspiration, or worsening breathing symptoms
Severe abdominal pain, especially after an injury
