The short answer
Unexpected worsening pain, wound discharge, fever or new leg swelling after hip replacement needs assessment. Sudden severe hip pain with loss of function may also be urgent. Chest pain or breathlessness requires emergency care.
Understanding the problem
Complications can include infection, blood clots and dislocation. The team considers symptoms and examination, sometimes with imaging or other tests. Do not try to manipulate a hip that feels out of position.
Care and next steps
Follow your medication, wound-care and movement instructions. Advice to stay active does not mean ignoring a sudden deterioration. If you cannot reach the usual team and symptoms are urgent, attend the nearest appropriate emergency service.
Prepare for your consultation
Before discharge, ask exactly whom to call during the day and out of hours. Keep the implant and operation details with your records. If a new symptom develops, note the onset and activity at the time. Explain medication changes or missed doses honestly so the team can assess the situation. Ask how routine concerns should be handled so you do not have to guess which route to use.
Common questions
Can I try to put a dislocated artificial hip back myself?
No. Suspected dislocation requires urgent professional assessment and treatment.
