when legs goes down

When injury happens in our body, we realize how important health is.After high altitude trek,suffering from severe swell and pain in my foot ,literally limping on the road,giving me sleepless nights.I was thinking about lame citizens where everyday living becomes a suffering ,let it be crossing roads to using washroom.so much I miss my walk now.
Nothing much to ask as boon from god except good health,let me get rid of this painful trauma
