Pain Straightening Knee
I am 39 yrs old, not overly active, but not a couch potatoe either. I have had no injuries to my knees. Over the past several months I experience difficulty straightening my knee after sitting for awhile. It is not a sharp pain, or throbbing pain but more like a sore ache which causes me to limp for a few minutes after I first stand. It eventually goes away, but the frequency and duration have been increasing over the past few months. Not sure if related, but I have also been extremely tired lately and although I get cold easily, it seems I am constantly cold lately despite that we are in the middle of summer.
