Still on strong pain killers and pain comes through sometimes also. At the first op just over 2 weeks ago I was diagnosed with endo on the womb and adhesion's on the bowel (they don't know if the bowel is endo related). I am surprised I am still recovering from the op, I don't know if it is the op itself or the mirena coil that I had put in at the same time. Can the mirena coil cause a lot of pain and dark spotting quite regular? Is that my body getting used to it?
