Hi Sir, I am Raj and I am 34 years old. I have stiffness in the spine from L1 to L5. It is severe when I am in sleeping posture and also when I am in standing posture. After some time it is getting cured when I take seating posture. I used the medication of Up-rice D3 60k for 12 weeks, Calcium 500mg for 12 weeks,fluxura D for 1month, Gaba pin NT for 6 months, Mayuril 8 mg for month, Thremodol-P for 1 month, Biclofin 10 mg for 1 month. I had the surgery of L4-L5 fliction in 2013. May I know why these pains troubling me when I am in sleeping and standing posture and why not in the sitting posture.
