Hope all goes well at OS,appointment. I'm sure you have been super tired with low iron levels.
This is from our library...Noise issues:
Clunking, popping and clicking noises tend to be caused by a temporary separation of the ball and the socket in the total hip replacement. It can be created as part of the surgical exposure and its accompanying trauma to the local muscles and the encapsulating tissues of the hip. Stretching, cutting, separating and or other types of necessary surgical trauma to the tissues that provide stability to the joint can temporarily create looseness in the articulation. In addition muscle tone may be less than ideal because of the badly trained muscles of the preoperative condition and all the fluid around the newly placed joint. The noises created under this type of conditions generally are painless and can subside once the capsule and muscles around the hip are fully healed. It occurs in the first few months after surgery and typically disappears progressively.
If this condition persists after 6 months or so, will not improve or has become painful it is important to consult your surgeon as it may indicate other conditions that may require his intervention or additional treatment.
