To Dr. Tamhankar,

My husband is suffering from lower back pain since he was 18 yrs old. He is 40 yrs old, On and off he gets the excruciating pain which feels like stiffened muscle.He has stabbing pain in buttocks sometimes along with lower back pain. He walks shifted to one side for few days before the pains subsides. Currently he is taking psoriasis treatment vitamin d3 with milk, vitamin a, e, c, and zinc capsule. Recent blood work indicated hyper thyroid but NO SYMPTOM PRESENT. So his doctor is not sure and asked to take another blood work after 3 months with complete th3, and th4.

MRI findings is as below.
Findings: The height and alignment of the lumbar vertebral bodies are normal. There is no evidence of compression fracture. A degenerative schmoral's node is present at inferior endplate of L4 vertebral body.
