ok so i totally agree ive got to correct the posture.

but how do i do this? im constantly thrusting/tilting my pelvic backward so to straighten my lower back when im standing and walking and whenever i consiously think about it. I now hate the feel of my spine pushing inwards i can just feel the pressure on the bottom of my spine it feels so wrong sometimes.

Is it ok to constantly be doing a pelvic tilt??.
I think you need to get some help with this. Someone needs to assess your problem. What you are doing may not be a very efficient way of dealing with the problem. It is hard to be objective about such issues so get a physio to assess your spine and posture.

Anyway i want to run something else passed you.. ive noticed the other day whilst doing some stretches. - my one side of my rib cage is petruding forward more than the other side. You cant notice looking straight at it, you have to look down my body at my toes. so either one rib cage is bigger or being pushed outwards or is twisted..
Most likely is htat you have a mild Wikipedia reference-linkscoliosis - that the spine is twisted and rotated a little. It may or may not be significant. A lot of people have mild scoliosis and it doesn't cause them any problems.
