Lower Back Pain. Need suggestion.

*Please read it fully* I have back pain from 1 year which is from the lower back to throughout the left leg. I have consulted few doctors in my home town. They said it's a minor disk bulge which is visible in the MRI report. They prescribed few medicines like nerve relaxers , pain killers and vitamins. The pain was less while in this treatment period. I was advised to used lumber belt and traction for a period of time. My back pain is gone  it's more or less from the beginning. But the problem is I have problem in walking and pain in the leg. I came to Bangalore for treatment and consulted few doctors. 1st doctor said the MRI scan is not properly visible and there is nothing to worry about the report. But according to my condition he said there may be a tumor in the spinal area which can be only confirmed by a new MRI and Blood test. 2nd doctor said it's visible in the same MRI report and nearly forced me for a surgery. I'm very much confused about my situation. Need suggestion.
