So, today, I went into the barn in the morning, before school. It was dark, and I have to go in the barn to switch the lights on. Well, I didn't know my mare was loose, and we scared each other as I rounded the corner. She kicked out, and just caught me on the hip. I tied her, and went to get on the bus. My hip didn't start hurting until mid way through the day. When I got up, I had a very sharp pain in my hip, that caused me to sit down again. I hobbled around for the rest of the day. It didn't bruise, so I didn't think that she kicked me that hard. After school, I got mom to drive me to the hospital. He said it was fine and to take a Tylenol. Well, here I am, almost 15 hours later. It still hurts. It almost feels like its rubbing against something. Its still not bruised, and it is not tender to the touch, just when I walk or sit down. Below my ribs is very sore too. I have no idea why. What do you guys think ? Should I go to the ER ?
