i have got a severe back pain..its hurting.. remedy?

Back pain is usually occurring when you have bad postures in all your day to day chores.The best remedy for this is by standing with wide open legs 1 foot apart.Then do a grind to the left for 1 to 8 counts and back from 8 to 1.When your are done do again the grind but his time to the right with the same counting.You can do this exercise for 3 sessions or about 5 minutes duration.
