I would reiterate that you go see a PT.
That said, the advice to "don't do any exercises which involve hamstrings and let them heal." is not good general advice because it depends on where in your recovery you are. Hamstrings need to be used unless the injury is recent and acute. You need to find exercises that don't aggravate the injury. Weak hamstrings will just get reinjured. For me, hamstring curls feel fine, for example. Barbel squats and deadlifts not so much.
If you look up the stages of hamstring rehab, only the first stage do you fully rest the hamstring, otherwise you need to be doing strengthening exercises.
