I blame my pressure for that

i also suffer from LBP, for very long time and i also have aneamia, but it wont really impact one's lifestyle. tell you one thing, maybe being active is the only way to combat LBP, since it is not curable but you can prevent the symptons. also try to have a die that is slightly higher in salt than normal diets, that will help your elctro-equilibrium in your body fluids.

i think it has some connection.when my blood pressure is low i feel same condition...very sleepy irrespective where i am...in class room or in my home or out in market... but i wonder if this condition lasts for years...

Oh I am pretty sure it does. Your brain and muscles have to get enough blood flow to function at top speed. If it isn't flowing well you can't expect any of your organs to function as they should.
