with your heavy activity saturday, you could be dehydrated if you didn't drink enough water and fluids.
alcohol can cause dehydration as well.
lack of sleep can cause headaches.
have you tried any tylenol and drinking more water at this point to see if those can help?
if your headaches continue, you should see a doctor and get an evaluation.
pressure in that area can be from many different causes.
if your symptoms have persisted after massage therapy and you have had rest and drinking enough water, you should see your doctor about it.
you should get a brain MRI scan and also get your blood vessels checked.
there are blood tests like ESR, C reactive protein which can check for inflammation of blood vessels like giant cell arteritis which can cause pressure in the temple area.
it doesn't sound like you have tried any tylenol or aleve and you can try this as well
