Shockwave Therapy for Lateral Hip Pain in Cape Town

The story is almost always the same. Pain on the outside of the hip, over the bony point you can feel through the side of your thigh. It is manageable during the day and then it wakes you at two in the morning, every night, and you cannot find a position that settles it. Someone has probably already told you it is bursitis.

Lateral hip pain is one of the most consistently mislabelled problems we see, and the label matters because it points treatment in the wrong direction. Getting the diagnosis right changes almost everything about what happens next.

Why is lateral hip pain so often called bursitis?

Because it looks like it should be. There is a bursa sitting over the greater trochanter, the bony point on the side of the hip, and for years the assumption was that pain in that area meant an inflamed bursa. The name trochanteric bursitis stuck.

When imaging studies looked more carefully at what is actually going on in these hips, the picture that came back was different. The primary problem in the large majority of cases is tendinopathy of the gluteus medius and gluteus minimus tendons where they attach to the greater trochanter. Bursal changes are often present, but they tend to be secondary and are frequently a minor part of the story. This is why the broader term greater trochanteric pain syndrome is now used, with gluteal tendinopathy as the main driver underneath it.

The practical consequence is significant. If you treat it as inflammation, the logical answers are rest, anti inflammatory medication and a corticosteroid injection. Injections often do give real relief for a few weeks, which appears to confirm the diagnosis, and then the pain comes back because nothing has changed about the tendon or the loads going through it. A lot of people arrive at the practice having been round that loop once or twice already.

Why does lying on that side at night hurt so much?

Because the tendon does not like being compressed, and lying on your side compresses it in two different ways.

Lying directly on the painful hip presses the tendon between the greater trochanter and the mattress. That one is obvious. What surprises people is that lying on the good side often hurts too, because the top leg drops forward and across the body, and that position pulls the hip into adduction, which drags the iliotibial band tight across the trochanter and squeezes the tendons underneath it.

So both side lying positions can load the same irritated tissue, which is why the night pain feels so inescapable. This is also the single most useful practical change we make in the first appointment. A firm pillow between the knees and ankles when lying on the unaffected side keeps the top leg from falling into that compressed position, and it is often the difference between a broken night and a full one within the first week.

Why do crossing your legs and hanging on one hip make it worse?

Same mechanism. Anything that brings the thigh across the midline of your body increases compression at the greater trochanter.

Sitting with your legs crossed does it. Standing with your weight dumped onto one hip, with that hip pushed out sideways, does it, and most people do this without noticing while waiting in a queue or chatting in a kitchen. Sitting in a low chair with your knees together and higher than your hips does it. Sleeping with the top leg flopped forward does it.

This also explains why a common piece of advice makes things worse. The instinct with a sore outside hip is to stretch it, usually by pulling the knee across the body or dropping into a figure four position. Both of those are adduction, which is compression, which is the thing the tendon is already objecting to. If stretching your hip feels satisfying in the moment and worse an hour later, that is why.

Reducing these compressive positions is not the treatment on its own, but it lowers the background irritation enough that everything else starts working.

Who gets gluteal tendinopathy?

Two groups stand out.

The first is women in their forties, fifties and sixties, where this condition is considerably more common than in men of the same age. Part of that is structural, since a wider pelvis creates a greater adduction angle at the hip and therefore more compression at the trochanter across normal daily activity. Part of it relates to the changes in tendon tissue that accompany the hormonal shifts around menopause. Many women in this group are not athletes at all and have done nothing unusual, which is exactly why the pain feels so unfair and so unexplained.

The second is distance runners. Running is a single leg activity, and every stride asks the gluteal tendons to control the pelvis while the hip is briefly loaded in a relatively adducted position. Runners who cross their feet toward the midline, run repeatedly on the same camber of a road, add hills, or step up their weekly mileage quickly are the ones who tend to present with it.

There is also a middle group worth naming. People who sit for long hours, particularly in low or soft seating, and who then train hard a few times a week. Long compression through the day plus a load spike in the evening is a reliable recipe.

How does shockwave therapy help the tendon?

In a tendon that has been painful for months, the normal repair process has largely stalled. The tissue shows disorganised collagen, an altered matrix, and small new blood vessels and nerve endings growing into the area.

Shockwave therapy delivers rapid acoustic pressure waves into the tendon through a handpiece pressed against the side of the hip. That controlled mechanical stimulus appears to restart the repair response, increase local blood flow and change how the tendon signals pain. Sessions take five to ten minutes, feel like firm rapid tapping, and are distinctly more tender over the trochanter than anywhere else. Most courses run to between three and six sessions about a week apart. There is no injection and no downtime, and it is common to feel a little achy over the hip for a day or two afterwards.

Shockwave is not a standalone treatment for gluteal tendinopathy and should not be presented as one. What it does is reduce the tendon's irritability enough that the loading programme can actually be progressed, rather than being repeatedly wound back because every session flares the hip. The shockwave course and the loading plan are one plan, delivered together by the physiotherapy and biokinetics teams.

Where does hip abductor loading come in?

This is the part that changes the outcome, and it needs to be built carefully because the wrong exercise in the wrong range will aggravate the hip.

Loading usually starts with isometric abduction, holding the hip pressed outward against resistance without movement, in a neutral position rather than a crossed one. That loads the tendons meaningfully while avoiding the compressed range. From there we progress into abduction work through range, standing hip control, and single leg loading such as controlled step downs and single leg stance work, before adding heavier resistance and higher volume.

For runners the programme also has to translate into gait, which means enough abductor endurance to hold the pelvis late in a long run, not just enough strength to complete a set. Widening a narrow, crossing over stride slightly and varying which side of the camber you run on are usually part of the plan too.

The biokinetics team at Peak Movement builds and progresses this programme, adjusting it week to week based on how the hip responds, while the physiotherapist runs the shockwave course and manages your symptoms. Gluteal tendinopathy is generally a three month problem rather than a three week one, and the strength work needs to continue past the point where the night pain has gone, because that is what stops it returning.

What does this look like at Peak Movement?

Peak Movement is on Strand Street in the Cape Town City Centre, with physiotherapy and biokinetics in the same practice, which is what lets the treatment and the loading programme run as one plan.

The first appointment is an assessment. We confirm the gluteal tendons are the source rather than the hip joint itself or referred pain from the lower back, test how your hip and pelvis control load, go through your sleeping positions and daily habits, and look at your running if that is relevant. If shockwave suits your presentation we explain why and what a course involves. If it does not, we say so.

Payment is settled at the time of your session. You receive a full invoice including ICD-10 codes, which you then submit to your medical aid yourself.

Frequently asked questions

Is my hip pain bursitis or gluteal tendinopathy?

In most cases of lateral hip pain the gluteal tendons are the primary problem and any bursal changes are secondary. That distinction matters because tendon problems respond to progressive loading rather than to rest and anti inflammatory treatment. An assessment can usually distinguish these clinically, and imaging is not always necessary to start treatment.

How should I sleep with lateral hip pain?

Avoid lying directly on the painful hip where you can. When lying on the other side, place a firm pillow between your knees and ankles so the top leg does not drop forward and across your body, because that position compresses the tendons. Many people notice an improvement in night pain within the first week of changing this alone.

Should I stretch my hip if it hurts on the outside?

Generally not in the way most people do it. Pulling the knee across the body or dropping into a figure four position moves the hip into adduction, which increases compression at the exact spot that is irritated. It can feel good briefly and leave the hip more sore afterwards. Loading the hip abductors is far more useful than stretching them.

If the outside of your hip has been sore for more than a few weeks, or it is waking you at night, book an assessment with the physiotherapy and biokinetics team at Peak Movement on Strand Street.
