Sometimes when you at least know the 'reasons' you feel bad you don't feel so crazy.  I guess you have something to blame for your general crudiness. I knew that hormone imbalance and estrogen were responsible for a lot of things, but I had NO IDEA to what extent. The joint and muscle pain I have been experiencing is a result of no estrogen in the body. The swelling and inflammation - same thing. Fatigue and depression, you guessed it.

Under normal circumstances, your body gradually goes through this change. But in my case, every estrogen maker in my body was totally shut down - and fast. So, all of the sudden, my body starts reacting- screaming and crying I should say to this change going on. My gynecologist told me this was going to happen - I just didn't 'get it' until it started actually happening.  I remember her saying " You will abruptly go through the symptoms of having no estrogen in your body and I won't be able to help you with hormone replacement therapy because of the cancer." and I thought- 'That's fine' and didn't think another thing about it. . . .until all these things started popping up. Like 10 pounds that came out of nowhere and joint pain and depression. I won't even go into the lack of libido part, but as my doctor reminded me,  I need to pay attention to it because it does affect relationships. All of these things do- not only my relationship with my husband, but when you have no energy to do anything but lay on the couch, it affects the whole family.
So, I do feel better just knowing that 'my symptoms' are part of the aftermath of cancer. She said in another year or so things should level out.
In the meantime, it's time to up my exercise, get my butt off the couch and force myself to do the things I know will make me feel better.

I did find an interesting article about joint pain , inflammation and the estrogen connection.
