Thanks for your query.
The most propable cause for your pain could be due to arthritic changes (wear & tear) in the hip joint as well as lumbar spine
down the leg may be attributed to a nerve compression by the degenerative discs and the facet joints in the spinal canal
Plain xrays of the Hip joint and Lumbosacral spine will show up the severity of arthritic changes. An MRI scan of the L.S.Spine is needed to establish the diagnosis of nerve compression.
Symptomatic treatment for her condition include
* Simple analgesics like Tylenol or Aleve as needed
* Moist heat fomentation over the painful areas which allows the underlying muscles to relax
* Local massaging of the painful areas with a muscle relaxant
gel will yield good pain relief
therapy and TENS (transcutaneous electrical nerve stimulation) may also be helpful.
I do hope that you have found something helpful and I will be glad to answer any further query.
