Brief Answer:
Regular physiotherapy will help.

Detailed Answer:
Hello,
Thanks for posting your query.
The treatment of spinal stenosis is done according to the severity of symptoms. Medicines are the first line treatment along with physiotherapy. If the patient responds well with medicines then physiotherapy helps in preventing further progression of the problem. Surgery is kept as a last resort to improve the quality of life of the patient.
The main treatment of such problem is bed rest along with pain killers and muscle relaxants. Muscle relaxants can help with your symptoms if used in appropriate dosage in combination with a potent analgesic. You can get these prescribed from your orthopedician.
Local analgesic gels and hot fomentation may provide a short term relief. You can use analgesic gels like Volini gel. Exercise is not advisable in the times of acute pain.
Using an LS contour belt of appropriate size might be helpful in providing support to back muscles.
Physiotherapy also plays a major role in treating such conditions. Epidural steroid injections have been used if oral pain killers are not very effective. Discuss with your orthopedician and an appropriate treatment can be planned depending on the response to medical drugs.
I hope this answers your query.
