Recurring headache
Most headaches are not caused by a serious condition, but a changing or worsening pattern, vomiting or visual symptoms should be assessed.
Hand numbness or nerve pain
Numbness or pain can have several causes, including pressure on peripheral nerves. The location and timing of symptoms and examination help guide the next steps.
Get urgent help
Seek emergency care for a sudden, extremely painful headache, a first seizure, sudden weakness or numbness, or difficulty speaking, walking or staying alert.
