Argythesheep! Welcome to the General Healthboards and greetings!
I am sympathetic to the headache. A cold ice pack may help a bit and or a massage gently with slight circular motions with fingers spread all over the head with both hands. Of course everyone is in charge of their own healthcare decisions and yes it has potential to be serious even if consciousness was not lost or did not seem to. Usually if consciousness was not lost things may be O.K. The emergency room could be seen and an MRI done to be sure there is no bleeding inside. Sometimes a slow bleed over a period of even days or possibly weeks can still be serious I understand. Headache and tiredness could be symptoms of the injury, illness or as stated a busy stressful time. I hope the needed support is obtained. I would not go heavy on medicines. Of course everyone makes their own healthcare decisions. Peace, sjb
