Hello
I don't think you need to worry now. I would keep an eye on it though, and if it gets worse, then it will merit a trip to the doctor. It could be that you have pulled a muscle, or strained in some fashion. If that is the case you will probably feel better tomorrow. Don't press on it a lot either as that can cause bruising and make it seem worse.
As long as you aren't having other symptoms, no fever, and your urine and stool are normal, I would just see what happenes over the next few days.
