Why Your Knee Hurts With Sciatica
The sciatic nerve branches into:
- Peroneal nerve (controls knee front/side)

Compression = misfired pain signals to knee joints.
7 Warning Signs Your Knee Pain is Sciatica-Related
Not all knee pain is sciatica. Watch for these red flags at our Lahore clinic:
- Knee buckling without injury – “My leg collapsed at Liberty Market”
- Burning behind knee (not inside joint)
- Foot pain + knee pain combo (sciatica highway)
- Numbness in calf and knee
- Pain worsens when sitting (driving in Lahore traffic)
- Nighttime agony (sciatica and knee pain at night)
- Hip-knee-foot “lightning strikes”
