has anyone on here had or waiting for a hip op. ? please can you tell me what the first signs of something wrong were? does this sound like i should go to the doc.? my hips seem to lock in position when ive been sat for a long stretch, such as driving in the car, when i cant straighten afterwards, and have to do it gradually, which takes a couple of minutes. this has happened off and on for about ten years, but recently, for the last week or ten days, my hips hurt where the thigh bones meet it, continually. it feels a bit like the thighs are trying to pop out of the joints, a sort of pressurized pain, and at the same time i am having a lower back pain, which is not on the spine, its between the spine and the hip bones. its mainly when i am walking. i'm reluctant to go to the doctor, if its just generall aches and pains, arthritis, just wondered if any of you have had this?
