1. since majority of signs are over Lumbar disc, it is probably a lumbar disc herniation which typically occurs between the age of 30 to 50 years, amd since there is involvement of lumbar nerve root thus "nerve root impingement" is also there.
2. are there any associated symptoms due to impingement: like leg numbness
, tingling, pain, and weakness? any Physical examination done to reveal diminished response to light touch and temperature changes, loss of strength, loss of deep tendon reflexes in the lower extremities??
3. elongated CFS intensity migth be due to obstruction of the spinal canal
[spinal stenosis], obstructindg flow of CSF.
4. as lower spine is involved [lumobo sacral], mainly lumbar thus lumbar degenerative disc disease is appropriate term: which means osteoarthritis
of spine [ please check with rheumatologist
, physical therapist or orthopedic surgeon.]
5. as we age the discs in our lower back naturally become more dehydrated and thinner, which is entirely normal.
6. Schmorl's nodes are protrusions of the cartilage of the intervertebral disc
and associated with necrosis of the vertebral bone, and should not be confused with tumor or infection [this relationship may be due to lumbar disc disease
, as the two commonly occur].
i. short-term bed rest with a support beneath the knees, nonsteroidal or steroid medication, pain medication (as necessary), and progressive ambulation followed by a back rehabilitation
and fitness program is needed. If nonoperative treatments do not result in improved symptoms then further evaluation and surgical consideration are warranted.
ii. Schmorl's nodes often cause no symptoms, but may simply reflect that "wear and tear" of the spine has occurred over time.
