What is dextroscoliosis and how to cure it?

It means your hump is on the right side. Just look at the mirror and you'll notice that your right shoulder is higher than your left. Surgery is the last thing that should be done if exercise and other treatments failed. Are you experiencing pain? How painful is it? Do you have difficulty in breathing? For pain just put a hot pack on your back for 20 mins. Then do some stretching exercise. Stand straight facing the wall, place your hands up touching the wall arms straight. Move your left hand across your right hand, then your right hand over your left alternately until you're leaning towards the right. Repeat that several times and 3x a day. Whenever your sitting or standing try to bend more on your right side to counteract the curve. Be conscious with your posture. If your scoliosis is a progressive type exercise will just slows down the progression of the curve and soon you might have a surgery to prevent your organs on your left side of your body from the compression. That organs are your lungs and your heart which is very vital. Hope it is not a progressive type. You must have a PT to help you in your exercise and will monitors you. If not just try the exercise I mention above.

I honestly don't know the answer but I just want to share that I too have it. I have known that I've got dextroscoliosis since high school. Same as yours, I found them out from the results of my x-rays. But since the doctors do not make a really big deal out of it and do not bring it up with me, I assumed it is not something that I needed to bother myself with. Now that you have mentioned that one might need to undergo spine surgery for having dextroscoliosis, I might have to research on that. Maybe I think it depends on the severity of dextroscoliosis.
