Stretching for Costochondritis is a great choice to make. If you do use these stretches, make sure you sretch after you walk or exercise so that you're warmed up. We don't want any more injuries. lol. Here are a few stretches to use at your own risk. You know I have to say that. =) If you want to try them, give it a go gently to see how you do. I also stretch out my legs, back, neck etc....but these four are especially helpful for costochondritis.
Start in the doorway with your hands on the door frame around your ear/shoulder level.
Step through the door with one foot and lightly stretch the chest.Once you have done this stretch with the hand at ear level, repeat with the hands high up on the door frame. As you are stretching, turn your head gently to the left, right, up and down. Continue breathing!
This stretch is more advanced, it stretches not only the chest wall, but the abs. When the abs are tight, they pull on your upper body and back, causing more pain for you. So keeping them loose is a great choice while healing from Costochondrits. Gently lay on the ball and open your hands to the side. Breathe.
This is another advanced stretch. Gently lay on the ball and hold your hands above your head. Don't hold your breathe. It stretches those lower abs- so they don't pull on your diaphragm and ribs.
