I had my mirena coil fitted in november 2004, it was uncomfortable to have fitted and I had severe cramping for about 12 hours afterwards. I had spotting for about 2 months but I was expecting that.Following this though I have experienced abdominal pain radiating from the left hand side,horrible back pain tiredness,and now have the beginnings of ibs which was diagnosed by my doctor last week I asked her if their was a link between the mirena coil and ibs and she said yes. All my other symptoms have been investigated by scan,vaginal swabs and blood tests all these have come back showing no problems so I have to think that the coil is causing me these problems,I am so glad I found this forum as now I will have this coil removed and go for sterilization as I am 46 with 5 children.
