A thorough history and physical examination is a good start when sorting out symptoms. X-rays will attest to specific bony/cartilage changes but x-rays don't always correlate with the pain. It is possible to have little pain and much damage on the x-rays or visa versa. It is important to treat the patient, not the x-rays alone. Secondly, x-rays of the back can reveal degeneration of the discs or small joints in the spine but the person does well. Contrary, the back may look degenerative and because of the subsequent bone spurring and symptoms as arthritis progresses, it is important to obtain an MRI to confirm nerve impingements that are suspected. X-rays alone will not show nerve impingement. As you can see, it is important to undergo the history and physical examination and tests that can confirm your diagnosis before treatment begins.
You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
