Hi lindkaye,
Sorry you had to join the the MS club. It takes time to go through the stages of grieving to reach acceptance. It may take time for you, or not.
I was in denial forever I think. I still want them to take away my MS dx, after about 30 years with it. But they insist.
Others can accept the dx and go right on living normally after a good cry.

You can always punch some pillows, works for me.
As for your question, I was on Avonex for a year and then Copaxone for 3 1/2years. Avonex my body did not tolerate. Copaxone gave me some issues and then it stopped working for me.
I am now on LDN as Sally and some others are. It was our choice. Sally and I were dx'd when there was no medications or treatments but steroids. They said back then, just live your life and maybe your case will be mild.
You should get a MS Specialist or Neuro who understand MS better than your doctor does. He doesn't sound well informed. The treatments should be explained to you, and you and whoever you confide in, can discuss the medications.
Never rush until you understand how these medication will effect you lifestyle. Some make you ill for days. Others may not. Everyone is unique. You have to decide what is best for you. I wish you good luck with your decision making.
Just relax, take a deep breath, and read up on MS disease treatments and MS symptom medication. Do not suffer. The Neuro can give you something to help you. The people here are wonderful when you have questions. They help me too.
