There seems to be no harm following the first week, however, there is little evidence that shows massage aids in a speedy recovery.
A laminectomy is when the lamina (the back bit of the vertebrae with the spinous process) is removed. Frequently a cage, or connecting rods are the placed to stop the vertebrae from moving. Laminectomies do work well and reduce pain when there is pressure on the nerves that comes from this bony section. But for general back pain, the evidence is poor; depending on how long the patient has been in pain for and the psychological state of the patient. Unfortunately, the results the patient want and what the doctor expect are different.
Muscle spasms are related to an irritated nerve. A muscle relaxant such as diazepam can be used in the very short term.

Physiotherapists would suggest this to be true. Muscle imbalance can cause the pain by having one set of muscle working too hard compared to the other. If the muscle imbalance is not the cause of the pain it may increase risk of injury and so, needs to be addressed. However, this also needs to be assessed and addressed by a physiotherapist through a range of stretches as well as a core-strengthening program.
