Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
His loss of bladder, bowel control may be because of spinal cord
involvement from Bone TB or just due to extreme weakness due to the age and disease.
But cord involvement is a serious affair and an MRI
must have been already done to look for it?
Age and bone TB is a grave combination and needs careful medical attention.
You may re-consult your doctor. Keep a watch on conscious level, jaundice
which can occur due to treatment or disease both.
Treatment takes weeks to take effect.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries. May I request you to rate your experience here before you close.
Thank you and Good luck!
