Nerve Damage in Spinal Cord

I was curious, My mother in law has been diagnosed with ms about 3 1/2 years ago, she has nerve damage in her spinal cord, (Which is related?) She's 56 and she's can walk, and do most things, but she has to limit herself. My question is this, She uses Copaxone which she injects every day, the cost of this is outrageous, she is tempted to stop taking it and told her doctors, but they advise against this, as this could cause an extreme exacerbation, can she utilize any of these remedies with her current medication?
