What can be wrong with my son??

**Update**

Took him to get looked at. Borrowed a family members car because hubby had to work. He would have came home if he had to but it’s his second day at manager. Anyways he is fine they think it’s just a sprain. Just needs to take it easy for the next week.**

Yesterday and this morning my son has been complaining of neck pain. He also says his arm and leg hurts. But mainly his neck and jaw hurts. And he has a slightly elevated temperature but not over 100. His neck also feels hot to the touch. He’s 5 and gets a bit crazy. I liked to do flips and jump around so I don’t know if he may have injured himself or what. Have any of y’all dealt with this? I gave him kids Motrin and gonna try to wait it out until his dad gets off work to take him to get seen. But just wondering if any of y’all have experienced this in your child.
