An AskHer answer: what is known, what depends on you, and what only a clinician can decide.

Nobody asked this one. AskHer’s editorial team wrote the question to open the topic. It is not anyone’s submission, and nobody’s own words are in it.

The short explanation

No, surgery is usually not the only option. Many people with a disc bulge pressing on a nerve improve with non-surgical treatment over weeks to months, including physiotherapy, staying active, pain relief your doctor advises and sometimes an injection near the nerve. Surgery is generally considered when there is severe or worsening weakness, loss of bladder or bowel control, or when pain remains severe and limits life despite a good trial of non-surgical treatment. Two months of leg pain is a reasonable time to review the plan with your doctor.

What depends on your situation

The parts of this that change from woman to woman. Uncertainty is stated, not hidden.

  • MRI findings do not always match symptoms. Disc bulges are common even in people without pain, so the decision depends on your symptoms and examination as well as the scan.
  • Your general health, the impact on daily life and work, and what you prefer all matter. It is reasonable to ask for a second opinion before surgery.
  • A physiotherapist can guide exercises that support recovery.

What this answer cannot determine

The boundary of online education. These need a clinician who can see you.

  • This answer cannot tell whether you need surgery. That depends on your symptoms, examination and scan, assessed by a specialist.

Questions for your clinician

Take these with you. You can add any of them to an appointment card.

  1. Is my nerve compression severe enough to need surgery?
  2. What non-surgical options can I try?
  3. What are the risks and benefits of surgery for me?
  4. Should I get a second opinion?

When to seek help

Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.

Emergency — call 112 now

  • Call 112 or go to the nearest emergency department if you have numbness around the genitals or bottom, loss of bladder or bowel control, or weakness in both legs.

Get help the same day

  • Get care the same day if your foot suddenly becomes weak or you cannot lift it.

Raise it at a routine appointment

  • Book a routine follow-up to review your treatment plan.
