Be sure to check out our Health Pages too Scout. They have lots of information to learn about MS and even more stuff about the reality of living with it. You can find them by moving your cursor right and scrolling up. You'll come to four shortcut icons near the top. Click on Health Pages.... or just go here.
Just to be clear about any possible Copaxone / Cushing connection....
"Infrequent" occurrences are reported by somewhere between one tenth and one hundredth of one percent of all users (notice: WAY less than even 1%). To me that means a few people taking Copaxone also ended up with Cushing’s. Who knows why? I'd be looking for a more common cause if I developed Cushing’s. I'm more threatened by MS than I am by Copaxone but only you can decide the risk balance you feel comfortable with.
JMO, I think activity limitations, metabolism changes that can come with MS and some of the drugs used for symptom relief are bigger potential offenders in the weight control department. I share your struggle so I understand weight control concern in theory. In reality, as my symptom intensity increases my concern shifts in favor of relief.
Hope you stick with us. We are all here learning together.
