Suggest Treatment For Lumbar Disk Issues

My father is 70yrs old and has a lumber disk issue, told that due to compression in the disk the blood flow is restricted and therefore legs become numb..He has under gone treatments like traction, homeopathy, exerciess etc.

Please advise if it can be completely cured. He has also consulted oxymed at Nandanam. Could you please brief about your treatment and % of remedy, duration of treatment etc.
