My dad can not walk not even stand for seconds. His both legs are sensed ton of weights and heavy. Ncv ,x-ray, mri reports say he has radiculopathy and lumbar spondylosis and slipped disc and nerve problem in legs. But he can move his toe fingers and leg very little but legs are sensed heavyweight. Now his sense are reduced in legs. We did physiotherapy for 3 months and taking pregabalin nt tab according to a doctor. His irritation feel is reduced but he can not walk. It is getting worse. His age is 70. Sir Please help what we will do?
