Thank you for posting your query.
I have noted your symptoms.
The most likely cause for your pain could be a pinched nerve
in the lower back. This can be evaluated by an MRI
scan of lumbo-sacral spine.
Regarding the possibility of MS, it seems unlikely as the disease would not remain quite for more than 20 years, if left untreated. Also, for diagnosis of MS, MRI of brain and spine are the first choices, not the spinal tap
I hope my reply has helped you.
I would be pleased to answer, if you have any follow up queries or if you require any further information.
