I dont think you have torn a hip flexor. If you had then it wouldnt hurt in your glute it would be the front of your hip/top of thigh.
Something that I have found to help with deep soreness and stiffness is rolling on a baseball.
I also find hanging leg raises quite theraputic for lower back and glutes.
