Sciatica nerve Pain. Of this problem.

I have been suffering from sciatic nerve pain in my left leg since last 6 months.I was badly affected with this disease as I was unable to walk properly,unable to bend myself down,unable to sneeze(as that was directly targeting my leg pain) and stop lifting any kind if weight then I was treated at different clinics and were passed with different advises for treating this problem. I visited a physiotherapist,a doctor and an Ayurvedic treatment center simultaneously then I feel some relaxation in my pain but now I don't know from where I get this relief. Now, I am able to walk and do all my daily routine work and can carry some weight as well "but still feeling some pain at same point" at the time of sitting bending and sneezing. I feel that disease still persists and want to be free completely Could any one please suggest a way to get rid of this problem.
