Hi Monica and welcome,
21 prescriptions sounds like a lot a medication besides the Copaxone. Maybe one of your meds is making you feel heavy, down and out, and lacking in enthusiasm for getting well and getting your life back on track.

MS does have the 5 steps of grieving, and surgery for the back is no picnic in the park, but the back should heal with time. Have you gone to PT? Do you have any friend or support person you can talk to and rely on?

You should discuss these feelings you are having with your doctor, Neuro, or another doctor if you need to. He/she can evaluate your medications and you might be surprised that you are bouncing back in no time at all.

I had about 15 or so major surgeries for many different problems including the back. It drains you for many months. It is another issue to grieve over.

You need to talk to us more on here and rant, vent or do what will make you feel better. Just writing down how you feel helps. We are all here to help and support each other when needed. Join us.
