I have muscle spasms in my back due to a herniated disc. When my back is bothering me walking and sitting aggrevate the situation. When the pain is intolerable I require bed rest and lidocane patches which after an hour are totally effective. My question is: I am going to Europe next month which will be all sitting (seven+ hours on the plane) and walking. Are the patches taking care of not only the pain, but the problem - or will I be worse off when the lidocane wears off each day because of the sitting and walking?
