Hi Thank you for your question to HCM. These findings indicate that the dimensions of the spinal canal have changes. The space available for the nerves has been compromised and that is leading to compression of the nerves. For my patients I always interpret the MRI findings in relation to clinical signs and symptoms. Specifically the stenosis you have mentioned can cause right leg pain on the back or front of thigh. It may also cause a feeling of pain/heaviness or numbness in legs particularly on standing or walking or even weakness of feet/toes in some cases. If this is the case the narrowing discs are the cause of symptoms. Pain medications like ibuprofen, meloxicam, tramadol and lifestyle modification as well as physical therapy are the first line of treatment. Epidural injections in spine can be done if pain does not respond to these. Pure back pain without any leg pain/tingling/numbness is unlikely to be caused by these findings in MRI. Hope this is helpful. I would be happy to answer any question you may have.
