If sounds like you are concerned about whether the head aches are PCS related or due to you lifelong struggle with head aches. I don't think the differentiation matters. If jogging causes head aches, you will need to either tolerate them or change your jogging to something that does not cause headaches.

At this point in recovery, everything becomes a test. The slower and more cautiously we introduce new activities into our daily activities, the better chance we have at determining if they are triggering symptoms. So add one new activity, wait a few days to see if it causes a return of symptoms before increasing the intensity of that activity.

Having recurring symptoms is much more likely as stress levels vary in our lives. I doubt your activities will damage your brain unless they result in a head impact. Jogging with a heavy pounding style of foot plant can be problematic so you need to work on jogging with a soft foot plant.

Your brain has been injured and is not sensitive to any impact or stress. This will be true for the rest of your life. You can develop behavioral disciplines that will minimize your risk of recurring symptoms. I have lived this way for decades. Sometimes, I will take on an activity knowing that I should expect to pay for that activity with a return of symptoms. It is an accepted risk with a risk benefit analysis.

We learn and move forward. That is how life works.

My best to you.
