If your head aches are manageable, I suggest you not be concerned about them. I have had times when manageable head aches persisted for 6 months, on and off after a head bump. Taking a break and relaxing often helped reduce them even more. Icing has usually helped.

Think of your head aches as a sign to still take things slow. Your writing style leads me to believe you tend to be an anxious person. Getting some help at reducing anxiety will be a big benefit. Also, Type A personalities tend to struggle more with PCS, so if you are a Type A, reducing anxiety and stress will be a bigger task.
