Tricia gave you some really good advice.

The more anxious you are the worse the pain feels. Everything seems worse when you're anxious and nervous.

Try to relax and, even if it's just for five minute stretches, tell yourself that you can make it till the 19th....or you can make it to the next 1/2 hour.....

Some of the symptoms you're describing do not sound like your typical MS symptoms. It sounds like a reaction to a medication or maybe just plain old anxiety. Stress and anxiety can manifest in lots of different ways.

I know this isn't what you want to hear but just try to stay calm and try not to focus on what's wrong. It's hard, I know, but most of us here with MS have to do this every minute of every day.
