Not knowing the brand and model of your machine makes diagnosis difficult. In most machines that have the bobbin case inserted from the front, you can try releasing the bobbin case and removing it. When my machine jams, removing the bobbin case releases all those threads that are twisted and knotted inside that are "holding the needle captive."
