I woke up a couple of days ago with a dull pain ache in my back left side. This pain was not felt in my bones, but felt like it was a pulled muscle. A day later, I felt tired lethargic and tired. I napped and didn't think anything of it. Today I have had sharp cramps in my abdomen, I should tell you I do not have a womb as it had to be removed about 10 years ago. My body is also aching, like I over worked every muscle in my body. Every so often I get a real chill and shake with coldness. I don't have a temperature and I do thane a flu or cold like symptoms. I have suffered from kidney stones in the past and I wonder if it might be that acting up again?
