I have an unexplained pain on the outside of my right hip. I have not fallen or bumped into anything. I do not have osteoporosis. I do walk every day, but have for several years, so it shouldn t have gotten strained by doing that. I did recently begin taking the Armour thyroid medication (about a week and a half ago). Could that possibly have anything to do with it? The pain is moderately severe when I first stand after sitting or lying down for a while. It seems to get better after I walk a little. It is tender to the touch also. I am 62 years old but in pretty good health. I weigh 132 pounds, and am 5 5 . I ve never had anything like this before.
