For the last month or so, it feels like every joint in my body is stiff and heavy, though I wouldn t really call this feeling pain. I am female, 58 years old, probably a little over weight, but not grossly obese. I have a desk job, so spend much of my day sitting, but I do walk at least a mile pretty much every day. Should I be concerned? I understand stiffness comes with age, but it doesn t seem like I should be this stiff at 58. Thank you.
