Dear Sir, I am 57 years old, 78 Kgs, 171 cms. I had been going for long walks daily (more than 10 kms) for last about 20 years. For last 02 years, I have been having back ache and now it has spread to legs. I was advised X-Ray and told that 02 vertebrates were pressed. I am undergoing physiotherapy for 20 weeks (traction, IFT, TENS.ultra sound, IR heat and SWD) There is not much of relief . Kindly advise. Pramod Kumar
