My son is 3 and a half years old diagnosed with spinal tb. He had recurring fever and localized lower back pain. There was pain in his legs behind the knees and stiffness. He had difficulty walking. His gait was antalgic. His mri showed l5 s1 affected with epidural abscess. Mis bilateral decompression was done. They started him on att 3fdc (pyrazinamide 450 mg, rifampicin 225 mg, isoniazid 150 mg based on his weight 15.6 kg) and wysolone 25 mg (steroid prescribed for 1 month and gradually tapered and stopped at the end of 2 and a half months). After 3 months there was a recurrence in tb which spread to l4 and l3. To make the spine stable we have done instrumentation. Is this recurrence due to wysolone?
