Hi manjunath thanks for the query
From the complaints you had described back and hand pain
could be related to wear and tear changes. Back pain
occurs if any of the lower limb is affected by polio which results in abnormal forces over the back bone. Regarding the hand pain I would like see an x ray
and comment. Some form of physical therapy
and back support an aid to relive pain. If you can provide with some X-rays and regarding the which part of the body has the polio we could suggest you some alternatives.
