You can often keep training with mild sciatica, which is irritation or compression of the sciatic nerve from lower back to foot. You should pause running when pain is severe or comes with significant numbness or weakness. Most sciatica improves within weeks to months but can recur, according to NHS guidance on sciatica. That pattern points to temporary changes for runners, not automatic retirement.

When should you pause running?
Runners with acute severe back or leg pain, significant numbness, or muscle weakness should pause until symptoms improve. High-impact loading can aggravate inflamed tissue, disc herniation, or stenosis, according to the Barricaid running guide.
A pause is not full rest for weeks. The NHS advises staying as active as possible, starting gentle exercise soon, and avoiding long periods of sitting or lying down.
How can you adjust training if symptoms stay mild?
Runners with only mild, manageable symptoms may keep training by cutting volume and intensity. Choose softer surfaces such as track, trail, grass, or treadmill instead of concrete.
Add core work, strength, mobility, and form work around the runs. Shorter, easier runs make it easier to notice whether symptoms stay stable.
Which warning signs mean stop now?
Stop the run and seek assessment for sharp or shooting leg pain. Also stop for pain spreading farther down the leg, new or worse numbness or tingling, weakness, or feeling unwell.
The NHS exercise safety advice says stop immediately and use NHS 111 if concerned, described in NHS exercises for sciatica problems. Get emergency care for sciatica on both sides, severe or worsening weakness or numbness in both legs, numbness around genitals or anus, or new bladder or bowel starting or control problems.
How can you support recovery while staying active?
Use heat packs and ask a pharmacist about pain options. Keep up daily movement and short walks rather than bed rest.
Do not rely on tablets to make a painful run safe. Paracetamol is unlikely to help sciatica and NSAID benefit is unclear. If home care fails after weeks, pain worsens, or normal activities stop, see a GP.
