Hi,
This pain is caused ultimately by pressure on your nerves.
There are a number of options to keep such pain under control:
Physical exercise: Physical exercise is undoubtedly the most important. You will have to do some regular exercises for your back; this is usually a very successful method.
Heat compresses: Heat compresses either superficially with a warm heat pack, or deep heat with ultrasound therapy, should be tried.
Medications: Drugs like phenytoin, carbamazepine, or tricyclic antidepressants such as amitriptyline are used to control pain.
Steroids: steroid injections may be given at the site of the pinched nerve.
Back support: A lumbar belt worn regularly by itself often helps to relieve the nerves. Braces, splints, orthopaedic shoes may be needed.
Lumbar traction: This is another option that you should discuss with your neurosurgeon. Traction often helps to relieve the pain making surgery unnecessary.
General measures like a firm mattress for sleeping, avoiding bending the waist forward, avoiding lifting heavy weights, should be practiced. Other measures may include vocational counseling, occupational therapy, etc.
Surgery: A repeat surgery of the spine is the last option.
In my opinion, for you, physical exercises, Lumbar belt, medications and occasionally steroid injections if the pain is too severe will be sufficient to give you a healthy life. You should consult your doctor for these options.
