I'm a 22 year old female. I had surgery for my scoliosis when I was 16 or 17. They removed one of my ribs and now on my left side its sort of uneven looking/feeling. What really bothers me is this twitching where the gap between my ribs is...you can SEE it move and it feels really weird from the inside. It started when I was in the hospital recovering from the sugery but I figured it would go away. It's been years and just this week and its bothering me more than usual. It kept me up most of the night last night!

Speak to your doctor, Kelton. I'm sure it's nothing serious but there may be some way of treating it. Did you mention it to your surgeon at the time of surgery?
