Sometimes an acute injury sort of resolves. You find you can work around it if you sit or stand just right, don't move too fast and skip the bottom cupboards in your kitchen. (Who really needs a bundt pan anyway?)
If this is you, stop reading and make yourself an appointment for acupuncture. Acupuncture for back pain is a powerful tool for acute conditions, but it is also very effective on older injuries. The World Health Organization has stated that "acupuncture is comparable with morphine in its effectiveness against chronic pain, but without the adverse effects of morphine, such as dependency." Really, it's that good.
One word of caution. If things get worse before they get better, don't worry. And don't stop coming! Moving your body back through the injury may cause a bit of discomfort as it unravels the problems. Going back through the place of initial injury and then resolving it at its root is what will have you standing and sitting up straight again. You may even be able to finally reach the cake pan!
