Ice packs and laying down if you can.
I was the same, luckily my husband is a chiropractor. Really helped me!
Make sure you are eating something every few hours and staying well hydrated.
I drink a glass of water followed by a cup of coffee
Acupuncture is the best it works for me, i never get headavhes and i go to the chiropractor also for my back every week and never have back problems.
I drink a little coffee for the caffeine but not more than what's recommended and that has helped me.
Plain Tylenol is fine, but no ibuprofen or aspirin! Hope that helps.
