Hello I ve been having severe pain in what I thought was my hips but the pain is really in the area right below my buttocks. It feels like my hamstring are about to snap. Very tight. The pain is less in the morning and intensifies as the day goes on. I do have a curves right knee that I ve been told someday when I m older ILL NEED A KNEE REPLACEMENT. MY knee is achey but nothing like the hips or hip flexor area. When I sit on heat the pain subsides somewhat but still there. I have difficulty bending down and getting back up because it feels like a muscle or hamstring is so tight. I m 58 years old. Used to be in great shape but this pain stops me from doing anything but walking and that only happens for a half hour before pain sets in. I feel like my hips could be out do place but not sure where to turn. I do have a Dr appt with my GP on May 3. Just looking for some insight as to what is happening to me.
