I've decided to start this thread, because I really want to find an answer to this.
Every time that I use an oral steroid, after about a week on, I get this awful pain in my lower back.
The pain is really bad when I first start to move, but the pain will die down after I'm in motion.
The causes I've found were "back pumps" which I don't really think it is since the muscles themselves don't feel sore. But let's suppose it's this, the most common cause I read is stress to the kidneys. Which makes sense except for one problem, I don't have a right kidney (removed following a car accident 9 years ago). So, it'd be impossible for that to cause pain on the right side of my back.
As for it being a liver problem, I don't suffer from any of the other common symptoms of an inflamed or damaged liver (as far as I know).
Do you guys think the oral steroids could be causing inflammation on the spine itself? Around the L1, L2 discs, it is mildly painful to press on.
