I was diagnosed with endometriosis in 2011 and I've had two lots of surgery once in 2011 and then again in 2015. The endo has returned yet again but rather than more surgery my consultant has asked me to try the mirena coil which I had put in last Friday. I wasn't sure what to expect and I know I need to give it more time, my consultant has asked me to try and bear with it for 3 months as a minimum. Since last week I have had lower back pain, a dull pelvic pain, nothing as intense as when the endo flares up but it is still there. The one thing that is worrying me is that for the last two days I have felt dizzy, lightheaded and nauseous with slight blurred vision, and just don't feel myself. I just wondered if anyone else has had these experiences with the mirena it and if they will pass soon or is it something I need to contact my consultant about. Feeling slightly worried about it.
