Short answer: sciatica is nerve pain from an irritated or compressed nerve root — usually a disc issue or a narrowed canal. PEMF may ease the pain and inflammation as an adjunct, but it doesn't fix the mechanical cause. The real recovery for most people comes from an accurate diagnosis, staying active, and targeted movement. Some warning signs — new leg weakness, saddle numbness, loss of bladder/bowel control — are a medical emergency. Start with proper assessment, not a device.
Get urgent medical care if you have new or worsening weakness in a leg or foot, numbness around the genitals, buttocks or inner thighs (the "saddle" area), or any loss of bladder or bowel control. These can be signs of cauda equina syndrome, which is a surgical emergency. Also see a doctor promptly for sciatica with fever, unexplained weight loss, a history of cancer, or after significant injury. No therapy on this page substitutes for that.
What sciatica actually is
"Sciatica" describes pain that travels from the lower back or buttock down the back of the leg, following the path of the sciatic nerve, often with pins and needles, numbness or weakness. It happens when a nerve root is irritated or compressed — most commonly by a herniated (bulging) disc, sometimes by spinal stenosis (a narrowed canal), and occasionally by muscular or other causes. The key point is that sciatica is a symptom of something, and the "something" determines what actually helps. That's why a diagnosis comes before a device. If your picture is more of a narrowed-canal pattern, our write-up on PEMF and spinal stenosis goes into that specific cause.
What PEMF can — and can't — do for nerve pain
PEMF delivers pulses of a low-frequency electromagnetic field, and the aim with nerve-related pain is to reduce the surrounding inflammation and discomfort so you can move and rehabilitate more comfortably. Some people find that genuinely useful. What PEMF does not do is repair the disc, decompress the nerve root, or widen a narrowed canal — the mechanical causes stay mechanical. So its honest role is supportive: an adjunct that can take the edge off while the real work — movement, nerve mobility, time, and treating the cause — does the healing. Our broader piece on whether PEMF actually works sets out the evidence picture across conditions.
What actually drives recovery
For most people, sciatica improves over weeks. The things that move the needle are an accurate diagnosis, staying as active as the pain allows (prolonged bed rest makes it worse), and a targeted physiotherapy and nerve-mobility program. Pain relief has a role so you can keep moving. Adjuncts like PEMF and radial shockwave can help the pain and the muscular tightness that often rides along with sciatica — for the muscular part specifically, the combined shockwave and PEMF approach is what we use. Persistent, severe or red-flag cases need specialist assessment, imaging, and occasionally injections or surgery.
How we use it, honestly
In the clinic, we start by working out what's actually driving the pain and screening for anything that needs urgent or specialist attention. If it's ordinary sciatica settling on its normal course, PEMF combined with radial shockwave can support comfort and the muscular component while you get moving again — reassessed at around session three, alongside a movement plan. If it isn't, or if red flags appear, the right move is a referral, and we'll make it. We'd rather send you for the right scan than sell you sessions.
Radial shockwave + PEMF for pain at ₱2,500 per area, typically 3–6 sessions with assessment included, alongside a movement plan — and honest referral where imaging or a specialist is the right next step. See the pain service page or what PEMF costs in Manila.
