Probably bad. lol. I know I did injure my back when I was in my early 20s. Paying for it now. I had the surgery to remove part of one of the discs that was compressing the nerves. Then I got a CSF leak, leaving me in agony for weeks, which resulted in a large lump on my back. I say mind your back people, because back surgery really is the last thing you want to have.
On saying that, this lump has been getting bigger and bigger. People are going to call me crazy for saying this, but my mum suggested that I go to a faith healer. It's one of those things where you're like "ah sure, why not, it can't do any harm, right?" I am catholic, so I suppose it wasn't THAT massive of a leap of faith. The healer knew what was wrong with me before I even told him. He was like "give it 4 weeks and come back to me" and I did what he told me to do in the meantime. It's been 3 weeks and the lump is almost gone. It was like it spontaneously halved in size one night and while it's still there, it's pretty flat and getting smaller. I am booked in for an MRI in two weeks time, but by the looks of it, it might be gone by then.
That's not normal actually. It shouldn't be gone that quick since it was continually growing and they were discussing an intervention. Hence the MRI to see what was happening. Make what you want of that one.
But... bottom line is that you only have one back, so if you are doing something wrong like bad posture, correct it. Make sure to build up your core muscles. I'm only in my 30s and suffered already. My cousin who is in her 20s had to have a back op too, but she came off luckier than I did. She's a dancer, but at the same time, her core muscles were weak. Something to think about.
