Postural Kyphosis

I have a great tendency to believe that I have Postural Kyphosis due to the arch in my upper back and my head being pushed forward a little. I believe this began taking effect right-at or during puberty sometime. I have been overweight through my childhood and teen years which has helped contributed to this issue. I will say that do I have pains from it and I believe my breathing has been affected by this. My left shoulder has a very messed up tendon (I'm assuming) or something that causes pain while standing for a duration.

In a few weeks depending on costs and such I may go to a chiropractor and find out how I can fix or at least attempt to correct my issue. It would be nice to be able to lay down on a flat surface without upper back and lower back pain.

Does anyone else have any issues similar? Similar experiences? Please share.
