When Pain Medicines Aren’t Working After Hip Surgery: What Older Adults and Families Should Ask About Now

Many hospitals have an acute pain service — a team whose entire job is pain that is not responding to the standard plan. You can ask for this by name. If your loved one has already been discharged, ask whether the surgeon can arrange an urgent review or readmission assessment.

Options after hip surgery may include PENG (pericapsular nerve group) blocks, fascia-iliaca-type blocks, and periarticular or local anesthetic infiltration approaches.

Systematic reviews published between 2024 and 2026 suggest some of these blocks can reduce opioid use after total hip arthroplasty — but results vary between studies and the certainty of the evidence is often low. They are also strictly clinician-delivered procedures performed by trained anesthesiologists, never something to arrange privately or improvise.

Scheduled acetaminophen (paracetamol) is a common foundation of opioid-sparing plans, but suitability depends on liver function and other medicines. Ask the surgeon or pharmacist directly whether it is right — we deliberately give no doses here.

Important: never combine multiple products that contain acetaminophen. It hides inside many combination painkillers, cold remedies and sleep aids, and accidental doubling is one of the most common medication errors in older adults.

Pain after hip surgery can be inflammatory, muscular, neuropathic (nerve-related), mechanical — or a sign of a complication such as dislocation, periprosthetic fracture, infection, clot or nerve injury. Each of these needs a completely different plan, so the first step is a diagnosis rather than a bigger dose. Ask explicitly: “What do you think is causing this pain, and how will we know if it's something else?”

Physical therapy, careful positioning, the right walking aid, and surgeon-approved early movement all reduce pain over time by preventing stiffness, muscle loss and complications. Follow hip precautions and weight-bearing instructions exactly — pushing past them can cause the very injury you are trying to avoid.

If the surgical team approves it, cold can take the edge off. Protect the skin with a barrier, keep sessions short, let the skin fully rewarm between applications, and avoid cold entirely where circulation or sensation is impaired — including a limb still numb from a block.

Poor sleep, dehydration and constipation all amplify pain and all are common after hip surgery in older adults — constipation especially with opioids. Adequate protein and calories support healing and protect muscle. Ask for individualized nutrition advice rather than a generic target, particularly with kidney disease, diabetes, heart failure or poor appetite.

Burning, electric, shooting or numb pain can indicate nerve-related pain, which often responds poorly to opioids no matter how much is given. Ask the team whether nerve pain is involved and whether a targeted non-opioid prescription would be appropriate. We do not recommend or dose any specific medication — that decision belongs to the prescriber who knows the full medication list.

In older adults, stacking sedating medicines — opioids plus sleep aids, muscle relaxants, antihistamines or anti-nausea drugs — can cause falls, low blood pressure, confusion, slowed breathing and delirium. A 79-year-old recovering from a second hip operation cannot afford a fall. Every added product, including over-the-counter ones, should be checked with the pharmacist.
