Hi I have been reading this site for a couple of days, I always look at posts but never reply but had to this time. I am on my 8th year of the mirena coil. For the past 6 months I have been to A and E and im having all sorts of tests for something unknown. My symptoms are like a lot that have been posted up here. I came across this site accidently. I am a shadow of who I used to be, im only 32. Having bad anxiety, heart palpatations, can barely walk in the mornings from stiff legs, pains in muscles, bad headaches, blurred vision and eye pain, aches in hips and shoulders. Bloods come back this week and if all is normal i think ill demand the mirena come out. Has anyone got any answers as to why so many are having these problems. Something i can bring to my doc and he cant tell me im going mad and shouldnt be looking at the internet. Thank you all for posting on this. Its great you all took the time to post so decided my turn. This has been of great help to me.
