JT,

Your experience makes sense. Relaxation is a big part of any recovery since stress or tension overtaxes the brain, just like taking the ImPACT test likely did. Many headaches are caused by muscle tension that effects the blood flow to and from the brain.

The most common therapy suggested for me has been relaxation techniques. Unfortunately, I mastered relaxation long ago. Relaxation therapy is a standard protocol so you were appropriate to seek help with it.

Once you have learned how to moderate your stress levels for the long term, you will get an idea of any residual concussion symptoms.

Have you every had any Physical Therapy for your neck? Or chiropractic treatments for your neck? Neck injuries are commonly overlooked after a concussion. But, if the head was traumatized, the neck was also impacted.

Sometimes, a PT will have a good massage therapist on staff who can help with neck and shoulder muscle massage.

As the old saying goes, "Doctor, it hurts when it do this."
Doctor replies, "Then stop doing that."

If you find something that seems to help, keep at it.

My best to you.
