I read your question and I understand your concern.
Treatment of MS depends also on its form. I will assume it's the most common relapsing-remitting form since it's the most common one.
The treatment consist in treatment of relapses (episode of appearance of new neurological deficits) with short term course of
steroids.
The long term treatment aims to prevent progression of the disease and further relapses. It's not curative but slows down the evolution of the disease. Traditionally it has consisted in treatment with Interferons or glatiramer acetate.
In these last years there have been plenty of new therapies, like
fingolimod,
natalizumab, laquinimod, etc, which have shown some promising results, but since it's a chronic disease, with a course of many years, follow-up studies of many years will be needed to assess their long term efficacy and safety. It also depends if they are available where you live, since they are very costly and some still in experimental trials, not approved for routine use in every country.
Of course
physical therapy and addressing and alleviating specific symptoms is part of treatment.
I hope to have been of help.
