Welcome to health care magic.
1.The history and symptoms suggest possibilities of
nerve compression at the level of lower
lumbar spine or hip joint pathology.
2.When joint space reduced the nerve get compressed and rubbing of the nerve occurs.
3.Itchy skin can be seen as a
skin infection / inflammation, but numb ness is seen as a radiating symptoms.
4. Treatment in this case includes back exercises including hip joint relaxation exercises.
5.Initially start with a x-ray lumbar spine and hip joints to see the bones and joint spaces - further treatment depending on the findings. However
MRI is investigation of choice.
Good luck.
