So I am 15 but since the time I was 7 I always had problems with my ribs and back. It wasn t until about my 7th grade year that I was diagnosed with Slipping Rib Syndrome. My ribs would constantly slip under and over each other and it was very painful. It still happens to this day, but there is a catch. The left side of my ribs in the top section is curved like a hill on a math graph. And no one has been able to tell me what is going on with that.
probably you have hypermobile joints which may be genetic in origin. The mobility may be excessive with ribs too. For structural abnormality, there may be calcium and vitamin D deficiency during childhood to cause this deformed ribs. Your doctor may like to advise to test blood levels of calcium, vitamin D and phosphorous if needs be and may cover any deficiency with prescribed supplements, medicines. You must have a physical therapy, expansion of chest exercises, breathing exercises, built up of chest muscles exercises to somewhat check hypermobility of ribsListen to soft music during exercise sessions and be happy best wishes,
