Could someone explain why the following is happening.

I have a friend who is injecting Avonex say in her left leg every Monday. The next day usual feeling bad happens but her right leg

will ache. Next week she would inject right leg and next day left leg will ache.

Anyone have any ideas why this is happening?


just a guess-but doesnt the right side of the brain control the left-and vice versa?

maybe not!
