Hi, thanks for writing to HCM.
Your description suggests that you have 
LUMBAR DISC DISEASE with 
RADICULOPATHY.
The initial management of your problem will be as follows -
* avoid lifting heavy weights 
* avoid forward bending activities
* Use a lumbosacral back support 
* Intermittent pelvic traction 
* Maintain optimum body weight,if you are obese
* 
Physiotherapy to strengthen your back muscles. Physiotherapy has to be done only after the acute pain has subsided.
* Judicious use of analgesics and muscle relaxants.
If all these measures fail to provide you relief, then surgical decompression may be an option.
Hope this information is helpful. Good luck
