I have studied your case with diligence.
For controlling pain MS you need a combined holistic approach to reduce pain.opiod
medication will give her pain free state , but these medication need to be taken regularly .
I will advise you to do regular physiotherapy
and exercises as she may get relief by these therapies.Meditation
and accupuncture will help as supporting therapy.
Some biologic injections have proven to halt progression of MS so consult your treating doctor to start those.
