My experience with exact same pain is a bulging disk in your back... It puts pressure on the the nerves in your spine to those areas. The worse it is, the lower the pain goes (hammies for me). My proscribed fix from a dr. was steroids for 5 days, and then Ibuprofen as needed, upto 8 pills at a time (2x 800mg prescription Ibuprofen) to reduce the inflammation at the point of swelling and then not to aggravate it....Pain will go away when the swelling is gone, but you still have a disk that can bulge, aggravate the area again...
