Do you take anything for your head aches ?

A week or two of rest is miniscule in the scheme of PCS recover. Besides, I doubt you could tolerate complete rest. You would still be mentally involved/anxious. Quiet activity is valuable to keep blood flowing through your head. Having some quiet activities to do when you have a head ache should be good. Take a break from the quiet activity from time to time. Close your eyes for a few minutes then resume the activity. Quiet activity is also a good distraction.

Do you spend your day with a smart phone in your hand ? texting, etc.
