Hi, Thanks for writing in. The bones of the spine are numbered. This numbering is from C 1 to C 7 in neck, D 1 to D 12 in upper back and L 1 to L 5 in lower back followed by S 1 to S 5 which are fused. You have an infection of the D 2 bone. Since this is TB infection, it requires a lot of time and regular treatment to heal. Your medications are correct and you should take them under your doctors instructions. Treatment can take 9 months to a year. Since repeat MRI shows healing is in progress you should continue treatment. The pain is usually due to the pinching of nerves at the affected levels. This happens due to the pressure of the affected bone and adjacent discs on the nerves passing through the foramen at that level. Please avoid doing heavy physical activities and try to maintain normal weight for your height. Eat nutritious for that is high in proteins and vitamins.
