Old l1 fracture from 1 yr ago, just in the last 3 months been having severe hip pain. been doing stretches but nothing is helping.

Pain not from fx: The old L1 compression fracture is most likely healed at this time and thus not the proximate cause of your pain. There may be bone pushed into the spinal canal eat the time of the fracture that is the cause of the current pain or a change in posture related to the fx is the cause of the current pain. An MRI or ct will show if the path of a root is being compromised. Otherwise, exercise and time.

Sciatica: Pain in the distribution as you suggested describes the pattern of the nerve that travels in the leg called the sciatic nerve. The sciatic nerve is not the cause of the pain source, it is the result of an irritated nerve typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease requiring further evaluation by a spine specialist.

See below: Depending where pain is in hip, could be trochanter bursitis or labral tear.
