My mother have pain in legs heel and on both side of heel. We have consulted too many doctors but there is no benefit. What can I do.

Nothing much to worry. You have not mentioned her age and does she have pain in other joints or body parts. And since how long she is feeling that pain. Sometimes the simple cause could be the footwear we are using. Ask her to start wearing Dr. Comfort sole chappals which we can easily buy from the market. Even at home she should wear this. STop wearing flat chappals. And secondly she can start doing footsoak in lukewarm water with a bit of rock salt before going to bed. It will overall relax her nerves and she will feel better.
