I also have cellulose but have for a while. I had the Mirena for 3 1/2 years though and never thought about whether it was form the Mirena or not. I was also on the pill (I think the mini pill and others as well before that) which I was haveing reactions to as well. I feel like a pear. I started hiking about a year ago-I did not feel like I lost much but felt healthier. by the fall and winter though, I just had no energy to even walk out of the house. I had the Mirena removed a week ago and still feel 100% better. I hope to start hiking again and see if I can lose the cellulose.
