You may have a slight kyphosis
. This is when the spine protrudes a little. I suggest you see a physiotherapist who will be able to examine your back and posture to assess whether there are any abnormalities. The physio may be able to suggest appropriate exercise to help improve your posture. Spinal surgery
is a major operation and not useful for correction of minor abnormalities or the spine.
