This lady worked from Nov 2014 in our house. One day I heard her asking for a chair as she had unbearable pain in her legs.
I discussed the pain in detail. She said that it is more than 6 year old pain. She was on medication for 6 long year.
I asked her to do the exercise suggested on this blog for 3-4 days and then share her experience.
After about 7 days she reported that there is no pain. And she has not taken any medicine since Dec 2014.
She still works with us and this information is updated every now and then.
