Hi. I recently and kind of still have a cold type thing I caught off my two year old. I had achy kneck and back around the gland area which has since reduced / gone away. However, I am now aching around the inner elbow areas, especially when I straighten my arms. Could this be a gland thing or it more likely a posture thing? I recently returned to work but only for two mornings a week. I do have a smart phone but am using it now less than ever (my husband keeps 'borrowing' it!)
