Joint pain and stiffness symptoms and conditions

I've never responded to a site like this, but now feel compelled to. I had my Mirena fitted 13months ago, after a friend recommended it on the strength of her excellent experience with it. I was on anti-depressants already, so haven't felt an overwhelming sense of depression, but have been thinking for the past 10 months or so, that I get way more tired, have an overall achy body often, painful joints and swollen ankles. All stuff I never experienced before. But the thing that really did it for me was the weight gain. I was only slightly over normal weight at the time of insertion but have been gaining weight steadily. Initially I thought it was just a bit over over-indulgence, but after weighing myself last week, I've made the horrifying discovery that I've gained 13kg in 13 months!!!!!!!! I've never fluctuated more than about 4 kg in my whole life, eat healthily and am normally active. Nothing has changed to what I was eating/doing before. I specifically searched the internet today to see if weight-gain is a problem. It's not listed as a major side-effect on the 'official' sites, yet I see it on many of the postings on this one.
And for those of you who are into alternative therapies, I had myself checked with a kinesiologist for dietary intolerances/allergies that could have caused this weight issue, and what came up is that the problem is progesterone. When she checked if my Mirena was a problem for me, it came up VERY positive. When checked if I should have it removed, the response was equally positive.
It's a pity, as I had none of the other problems mentioned and it's such a convenient method of bc. But in my case it's coming out, before I have to come out as a seriously obese 41 yr old!!!!!

I've taken Actonel 35 mg for about 2 years. I've stopped taking it. I have developed severe hip joint pain and stiffness. It has gotten progressively worse. First the hip tendons seemed to hurt and weaken, severe sharp shooting pain upon some movements. I have times where I injured the hip from simple things, like digging in the garden with a shovel. I am 52, am/was very active. Had breast cancer so the doctors keep testing for cancer in the hip, it's not there. X-ray show arthritis-type changes. The pain is getting worse, so I'm looking for doctors/treatment to help, stop, or reverse this hip pain. Actonel mentions joint/hip pain in the side-effects, anyone else have these problems?
