hamstring injury

I've got a major trigger point or pulled hamstring in the upper insertion to the glute. Don't ask me what caused it cuz I don't know. Is there any way I can do leg day or modify or should I just do cardio?? I wish I could do some quads at least, but I'm not sure which quad exercises would not involve hamstrings. Thanks
