Hi, thanks for writing to HCM.
Most propably you could have suffered a soft tissue contusion
possibly involving the muscles. So the pain typically occurs during movements of the inflammed muscles.
This is usually self limiting and recovers spontaneously with the following measures
* Give rest to the injured part and avoid activities causing pain
* use analgesic
medications as needed
* Do ice packing over the painful areas once in 2 hours
* Moist heat application may resolve the stiffness
Hope this information is helpful. Good day
