[|Human|] I was diagnosed with MS x 18 yrs, have been on Avonex x 17 yrs. I have had 7 flares requiring Solumedrol over the past 18 yrs. I am experiencing some saddle seat and bilateral lower extremity numbness x 1 week. Present symptoms do not feel like MS, I have been constipated, do you think that constipation can be a contributing factor for my current symptoms??
[|AI|]  I read your query carefully, and I understand your concern. I wouldn't exclude MS as a cause of these symptoms as a spinal debilitating lesion could have these consequences. It is not typical though, urinary involvement is more common. I wouldn't see constipation as a cause, rather as another symptom along with lower extremity numbness and saddle sensory changes. I think the origin of the symptoms warrants MRI imaging of the spine not only for the MS lesions which I mentioned, but also for the possibility of disc disease or a tumor compressing the caudal equine (the bundle of nerves leaving the spinal cord at the lumbar region). I hope to have been of help.
