Are those tanker knees?

My knees have been killing me for months and have been creaky for a couple of years. The pain has finally gotten to me, so I went to the doctor today. They want to do xrays tomorrow and probably a MRI and then we will see what we are dealing with. Hopefully nothing major, but when my husband (the tanker), hears my knees creak, he winces in pain. I guess it does sound pretty gross....
