<bot>: Hello, This MRI finding is not indicative of sciatica. Sciatica usually causes back pain irradiating in one or both legs, which is triggered by walking or sitting position. For this reason, I would recommend performing regular physiotherapy and checking your knees too (an X-ray study of both knee joints, coupled with inflammation tests). Take care. Hope I have answered your question. Let me know if I can assist you further.
