Ouch! My Arm

So I knew it would happen... actually I didn't. Layla is pretty good as far as getting sick, needing to go to the hospital, cuts and bruises. This all started when she wasn't moving her arm, or bending it. Almost holding it to her side. She would do it here and there for the first day. The next day I didn't really see her doing it, so I thought nothing of it. Layla never had a fall that would have drawn my attention to her needing medical help. The only recent thing was us being sick. On the third day first thing in the morning, Layla was once again holding her arm close to her side. My mom was the first person to notice so I told her about it again. We took her to urgent care. Layla is not one to like boys, guys,or men... whatever you want to call the opposite sex. Her doctor turned out to be of course a man. Well she didn't want him touching her arm nothing... So we couldn't figure out if it was pain or fear. We ended up getting xrays and that showed nothing except fluid. Fluid around her elbow joints. The doctor at first thought maybe it was fractured so small it wouldn't even show up on an xray... OR that because we were sick, the fact you are sick can mess with your joints. And since Laylas bones are not connected it just built up. So the next thing was to check if the fluid was infected. If so she would need immediate surgery. They had me sign off on all the paperwork before hand because if they needed to surgery they didn't want to waste anytime. Once I was in the process of doing that, it hit me like a ton of bricks. The doctor started going over all the risks of the surgery and complications that could arise. Why on earth was he telling me this now!? I could have cried. My dad had left me to get my mom from our house. I was sitting here with Layla contemplating life or death... That was all I heard when he was telling me that that was one of the possibilities that could occur with this surgery. I know I know what are the chances. But for me. What else was I going to think about. The chance that she might never use arm. I had to be strong for Layla... who was happy as can be as long as no one was touching her arm, trying to talk to her or asking her to move her arm. We spent the entire day at urgent care. About 4:30 one of the three doctors came in to tell me that it wasn't infected and that they would put a splint/half cast on her arm and just begin giving her anti-inflammatory pain meds and hopefully the fluid would leave within a week. Well two weeks later the fluid was gone. Xrays came back clear of fluid. The NEW doctor said that it can happen to any kid. Whether or not it was from being sick or her banging it, falling it while jumping on the bed. Something so minor can result in this. Yet I still get a horrible feeling in my stomach when I see parents grab their kids by their arms... or lift them by their arm. Babies and toddlers are fragile. They are not rubber and bounce back. You can seriously hurt your child. Would I want to go through that again?! But how can I prevent another injury from happening when we dont even know the cause from this time? I can't put Layla in a bubble. Children will get hurt. I am so thankful I dont have a boy though lol. Layla def. had her moments where she was unconscionable. I felt completely useless and the doctors bent her arm back and forth. In the end I'm so thankful she didn't need surgery.
