When there is no problem in x - Ray or scan any intervertebral disc reduction or spondylosis us ruled out. There is no radiating pain reported either. This paves the way to decide in favour of stiffness of lumbar vertebral joints. Best way is to take hot water baths and apply muscle relaxants thereafter. May drink turmeric powder 1/2 tsp twice in milk or hot water. OR take Haridra capsules. It s same thing. Avoid cold drinks and cool atmosphere say A.C. etc. Drink hot water. Avoid pain killers. But my own patients would be given Ayurveda s herbal Dashmularishta liquid twice daily and Tarunikusumakar kusumakar herbal powder 1 tsp at night with warm water every other day. These are safe and side effect less naturals. In four weeks everything is expected to be normal. Hope it helps you.
