Mirena and peripheral vision

I had my mirena fitted in 2000 when I was 40 years old. I have suffered with psoriasis since that time and only recently realized that maybe this could be linked to the hormone. I have spoken to my GP who insists that there could be no link and that it is purely co-incidental, however he can offer no other advise as to the cause of the psoriasis, so how does he know. I have tried all sorts of remedies to alleviate the psoriasis with no luck. I am now practically convinced that the mirena is the cause and am considering having it removed asap. I have also experienced palpitations for the last two years and have had all the tests and have been told I am fine. I also suffer from IBS. Has anyone else experienced similar?
