Does the mirena take away endo flares?

I had stage 3 endo diagnosed 6 months ago by lap and had an ablation. It’s been 6 months and my pain is back and quite severe. Impacting my job and my day to day life, I feel one again like endo has stolen my life. My gyno keeps suggesting the mirena, which I was hesitant to do as the pill makes me go insane and I really like having a natural cycle. But the pain has become unmanageable again. If I put the mirena in now, without having another lap, will it take away the stabbing/aching/lightning/concrete block always in my uterus and the other horrendous symptoms or will I be living with this base level pain, it just won’t get worse? I don’t know what to do, mirena is a last resort as I’ve had a terrible experience having it implanted and removed previously. I’d love to hear your thoughts/experiences. (Surgery every 6 months isn’t an option due to the time off work and how much the surgery costs each time, it also only gave me 3 pain free months)
