When hip or knee arthritis begins to dictate how far you can walk, whether you can sleep comfortably, or how confidently you use the stairs, finding effective relief becomes more than a question of taking a tablet. Arthritis pain relievers can reduce symptoms and help you stay active, but the right approach depends on the joint involved, the severity of arthritis, your wider health and what you need to get back to doing.
For many people, the best result comes from combining sensible pain relief with a clear plan to protect movement, build strength and address the underlying joint problem. Medication may be helpful, but it is rarely the whole answer when pain is persistent or function is declining.
What causes arthritis pain in the hip and knee?
Osteoarthritis is the most common reason for progressive hip and knee pain. It involves changes to the joint surfaces, cartilage and surrounding bone, often alongside inflammation of the lining of the joint. Pain can develop gradually, although an old injury, previous surgery, altered alignment or a sudden increase in activity may make symptoms more noticeable.
A painful arthritic joint may feel stiff after rest, ache at night or become increasingly difficult to trust during everyday movement. Knee arthritis can cause swelling, catching or a sense that the knee may give way. Hip arthritis is often felt in the groin, buttock or thigh and can make putting on shoes, getting in and out of a car, or walking uphill particularly difficult.
Pain relief should be chosen with these patterns in mind. A treatment that eases a mild flare after gardening is different from the support needed when walking distance has steadily reduced over months.
Arthritis pain relievers: the main options
Simple analgesia
Paracetamol is widely available and may offer modest relief for some people, particularly when pain is occasional or mild. It is generally better tolerated than many anti-inflammatory medicines when used correctly, but it does not reduce inflammation and is not effective for everyone with established arthritis.
It should still be taken within the recommended daily dose. People with liver disease, a low body weight or regular high alcohol intake should seek individual advice before using it routinely.
Anti-inflammatory medicines
Non-steroidal anti-inflammatory drugs, often called NSAIDs, can reduce pain and inflammation. Common examples include ibuprofen and naproxen. They may be useful for a short period during an arthritis flare, or when swelling is contributing to symptoms.
However, NSAIDs are not suitable for everyone. They can irritate the stomach and increase the risk of ulcers or bleeding. They may also affect blood pressure, kidney function and cardiovascular health. The risks are greater in older adults and in people taking blood-thinning medication or certain treatments for heart disease.
Topical anti-inflammatory gels can be a sensible first option for knee arthritis because they deliver medicine close to the painful area with less absorption into the bloodstream. They are less likely to help a deep hip joint, where the joint sits beneath more tissue.
If an oral anti-inflammatory is being considered, it should be used at the lowest effective dose for the shortest practical time, with advice from a GP, pharmacist or specialist who understands your medical history.
Stronger painkillers
Opioid painkillers may occasionally be prescribed for severe, short-term pain, but they are not usually a good long-term solution for arthritis. Drowsiness, constipation, nausea, falls, dependence and reduced alertness can outweigh the benefit. They may mask deterioration without restoring the ability to move comfortably or confidently.
This does not mean pain should simply be endured. It means that if stronger medication is becoming necessary on a regular basis, it is worth reassessing the joint and discussing treatments that may offer more durable relief.
Creams, heat and practical support
Some people find topical treatments, heat packs or a warm bath helpful for stiffness. Cold packs can be useful after activity if a knee is swollen or hot. A walking stick, used in the opposite hand to the painful hip or knee, can reduce joint loading and make walking safer while treatment is being arranged.
These measures will not reverse arthritis, but they can make a meaningful difference to difficult days. They are most useful when part of a broader management plan rather than the only response to worsening symptoms.
Why movement still matters when a joint hurts
It is understandable to avoid movement when every step is painful. Yet prolonged inactivity can weaken the muscles that support the hip and knee, increase stiffness and reduce confidence. The aim is not to push through severe pain, but to find tolerable, regular movement that keeps the joint and surrounding muscles working.
Targeted physiotherapy can improve strength, balance and walking mechanics. For knee arthritis, strengthening the quadriceps and hip muscles can reduce stress on the joint. For hip arthritis, improving mobility and the strength of the surrounding muscles may make daily tasks easier. Low-impact activities such as cycling, swimming and controlled strengthening work are often more comfortable than running or repeated impact exercise.
Weight management can also reduce load through the lower-limb joints, where appropriate. This is not about blame. It is about identifying every realistic way to make symptoms more manageable and to improve the outcome of any future treatment.
When injections may help arthritis pain
Injections can be considered when pain continues despite simple measures and is preventing rehabilitation, work or normal daily activity. They are not identical treatments, and their suitability depends on the joint, scan findings, symptoms and personal goals.
A steroid injection may reduce inflammation and provide temporary relief, particularly during a flare. The degree and duration of benefit vary considerably. It can create a valuable window for physiotherapy or an important event, but repeated injections are not always appropriate and should be planned carefully.
Hyaluronic acid injections aim to improve joint lubrication and may help selected patients, particularly in the knee. Platelet-rich plasma, or PRP, uses a concentration of the patient’s own platelets and may be considered in some circumstances. Arthrosamid is a newer injectable hydrogel treatment used for certain patients with knee osteoarthritis. These options need an individual assessment rather than a one-size-fits-all promise.
Injections can relieve symptoms, but they do not rebuild a severely worn joint. If pain is constant, mobility is significantly restricted or the joint is affecting sleep and independence, it may be more useful to discuss whether surgery offers a more reliable long-term solution.
When arthritis pain relievers are no longer enough
There is no single scan result or age at which joint replacement becomes necessary. The decision is based on the impact of symptoms: how far you can walk, whether pain interrupts sleep, whether you can work or care for family, and whether non-operative treatment still provides acceptable relief.
For advanced hip or knee arthritis, joint replacement can offer substantial pain reduction and restore day-to-day function. Modern planning focuses on matching treatment to the individual, including the shape of the joint, limb alignment, prior surgery and activity goals. Patients with a previous joint replacement that has become painful, loose, unstable or infected may need specialist assessment for revision surgery.
A consultation should be a discussion, not a sales pitch. You should understand what is causing the pain, which options are realistic, the likely benefits and limitations of each treatment, and what recovery would involve. For patients in London and Kent, a hip-and-knee specialist can help distinguish between a condition that needs time and rehabilitation and one that requires more definitive treatment.
Seek urgent advice for these symptoms
Arthritis usually develops gradually. A suddenly hot, red and severely swollen joint, fever, feeling unwell, inability to bear weight after an injury, or new calf swelling should not be assumed to be ordinary arthritis pain. These symptoms need prompt medical assessment to exclude infection, fracture, a blood clot or another urgent cause.
Living with arthritis does not mean accepting a smaller life. The most appropriate pain relief is the option that safely supports your movement now while keeping sight of the activities, independence and confidence you want to regain.
