The problem may not be in the blood flow but it may be in the spine (lumbar spine
) from which the nerve
supply emerges. However, a Physical examination is mandatory to assess this since there are variety of other causes that needs to be ruled out.
He may need an X ray
of lumbar spine to know the cause of problem. A Orthopedic surgeon or a Neurosurgeon are relevant specialist for this kind of a problem.
