Your symptoms are suggestive of a lumbar disc lesion. Pain around the back going down the leg, numbness of the leg or foot and tingling or itchiness are all symptoms of a disc lesion. Such lumbar disc pain is usually associated with sciatica.
Sciatica is pain along the sciatic nerve, which runs from your hips down along the back of the leg. It occurs due to the nerve getting 'pinched' at the spinal level.
There are a number of options to keep the pain of a disc lesion 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.
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.
Other measures may include vocational counseling, occupational therapy, etc.
Surgery: Surgery of the spine is the last option.
You will need to consult your doctor, if possible a neurosurgeon, for further investigations and treatment. You will usually be diagnosed clinically, but the doctor may advice investigations like CT scans or MRI.
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.
