Yes, sciatica and spondylitis can absolutely be confused with each other — and it's a really important distinction to get right. The pain pattern described, traveling from the back of the thighs, through the knees, and down to the ankle, sounds like nerve-related pain, which can actually be caused by spondylitis itself.
Here's why spondylitis can mimic or cause sciatica-like symptoms:
- Inflammation in the spine can put pressure on nearby nerves
- Extra bone growth (the body's response to ongoing inflammation) can narrow the spaces nerves travel through
- Even minor spinal changes from spondylitis can compress nerve roots, causing shooting pain down the legs Two weeks of that level of pain is serious and deserves proper medical attention. A rheumatologist or spine specialist can help determine whether the nerve pain is being driven by spondylitis activity.
An MRI is often the best tool to see what's happening — it can reveal inflammation, bone changes, or nerve compression that X-rays might miss.
Please don't wait too long to get this checked out. Nerve pain that persists or worsens needs prompt evaluation.
