My daughter fell down a flight of stairs while carrying a baby she sits for (she's 21) on Friday night. She held tight to the baby (no injuries) but took the brunt of the fall (hardwood stairs) on her back and tailbone. We went to the ER, had X-rays but they didn't check organs etc. and only prescribed Motrin. Her college health services put her on muscle relaxer yesterday. She is trying to keep mobile (using crutches and getting rides to some classes). Tonite she is complaining of female organ pain, cramping. She is not having as many BMs as usual (she's vegan). It's not her time of the month. She's also not really improving. Is this normal?
