Do you have any fronts going through...rain, barometric pressure changes, etc? I don't know where you live but there have been powerful storms in the US this week. That always makes me hurt more.
Try hopping in a hot shower and see if you feel better. That helps me with a flare. If it does, then relax, drink plenty of fluid, try to walk around as much as you can and hopefully this will pass soon. If it doesn't you might want to talk to your doctor.
