Hi. My name is Vinay. Am very sorry to hear about your Spine Pain. I hope you are getting all the Anti-Tubercular Medications for the treatment of the infection. That's the most important because you need to avoid further damage to the spinal column and cord.
Now, as to the pain. The main thing causing the pain is the collapse of the vertebral
body. When it collapses it will begin pressing against the spinal column. The only non-pharmacological treatments that are effective in this case are Physical therapy
(postural therapy in particular) and core strengthening exercises. Now remember you must go to e certified therapist to attempt these exercises as you don't want to make a mistake and injure your spinal coloumn even more.
So, in effect, your best avenue for pain relief is Physical Therapy. I would call your primary doctor and get a referral for that as soon as you can. Take Care and I hope you are cured of the disease in good time without too much injury
