my sister n law fell down the stairs, although the stairs are carpeted, she was carrying her 2yr old at the time and fell more awkwardly, she hit with much force the left side of her buttocks, not the tailbone but the actual cheek on about 4 or 5 steps but especially hard at one point...so she says now that she feels like she literally "broke" her butt; so I am wondering is there anything n that area that she could've injured or broken? I asked her if she pulled or twisted and she said she just hit extremely hard...she cant sit, stand, or even touch the area and is n so much pain its taking her breath, can u help me with this
