Hi Adamson77, do you mind me asking how old you are? It sounds to me like you're in perimenopause. I was going through the same symptoms that you have even without the Mirena. I was ready to chomp anyone's head off if they looked at me sideways. And road rage???!!!! OMG. I was actually terrified to get behind the wheel of a car out of fear of what I might do if some ahole cuts me off. And the sweating and the freezing.....don't get me started on that either. Yeeeesh!!! The only thing I don't have is the tremors. I do have tingling in my right arm and hand, but I can't blame that on the Mirena, because I got those pre-insertion.
Yeah, but everything you describe sounds like perimenopause. But then again, if you're young, it might just be the Mirena.
Best of luck to you. Zuza.
