Try and eat well and get into a regular sleeping schedule if you're already not. With this, your headache will hopefully resolve sometime in the near future.

As for headaches, there are many who endure years of headaches following their head injury. I currently am at almost 24 months of constant headache pain, though I know others here have suffered much longer.

If you have any other questions on management, coping, etc., there's a lot of great people, such as Mark, that have a wealth of experience.

Hope your headaches cease quickly!
