I have had Mirena insterted for over a year now since my first daughter was born. My symptoms have been bad but bearable. I've had severe cramping from radiating from my back almost like back labor it was constant the first 3 months and I just kept telling myself it would get better, and it has sort of. Now the cramping only comes while I am ovulating or during my "period". The periods are now super light almost non-existent, which is probably the only plus with this whole deal. I just started having the same symptoms of tingling and numbness in the legs, hands and feet. It happens all the time regardless of what I am doing. I get bouts of diahrrea here and there usually with the cramping and nauseau and sometimes dizziness. I have also developed ovarian cysts. My OB swears it had nothing to do with the IUD but I think it does. Anyone else having these bad back cramps??
