When to see a GP See a GP if you have these types of symptoms, particularly if you have a headache that feels different from the type of headache you usually get, or if headaches are getting worse, advises the NHS.
As the health body points out, you may not have a brain tumour, but these types of symptoms should be checked. If the GP cannot identify a more likely cause of your symptoms, they may refer you to a doctor who specialises in the brain and nervous system (neurologist) for further assessment and tests, such as a brain scan, it adds.
