I am not very sure whether you have multiple sclerosis or not. Because your MRI is normal. Please review your diagnosis by taking a second opinion from a neurologist who is experienced in treating multiple sclerosis.
Dear Lybrate User,
As you are describing, Your mother is suffering from episodic neuropathic symptoms.
Numbness in the extremeties is an important sign, that should be handled carefully in early stages. So that its complications due to sensory loss can be prevented.
Pain in the same arm and shoulder also points towards neurological dysfunction of any particular nerve.
There is many known causes of neuropathy for this age group. That needs to be ruled out. Diabetes mellitus is most common and important cause.
Vitamin B12 deficiency, sometimes vitamin D deficiency.
Sometime Hypothyroid pts also presents with numbness.
For the list of investigation and individualised management tailored for this patient, you should consult a physician.

Dear lybrate-user, L4-L5 disc prolapse is very common at your age. Most of the cases (almost 80-90 percent) improve with conservative care including best tolerable medical management, Physiotherapy and lifestyle measures. It takes approximately 6 weeks to 3 months if you are very compliant. I think you may need to increase/ optimize your medications if you are satisfied with your therapy / lifestyle measures. Attend your doctor for the same ; but please inform him urgently if you have following symptoms like progressively increasing symptoms (sensory loss /weakness, difficulty holding urine/ stool or severe cramps in legs after taking only few steps.
Hopefully you will improve very soon.
Wish you all the best!
