You're never too young apparently
You're apparently never too young for a herniated disc, or in my case, two. I'm twenty three and I started training BJJ about a year ago. I became immediately addicted of course. Soon I was training every single day. I got into great shape. Made a lot of friends. Generally having a blast.
So about seven or eight months into training I started getting what felt like really tight hamstrings. Like a fool, I pretty much ignored it. I tried a little bit of stretching but it didn't really help. Kept on training. On January 31st I got my blue, and within two weeks of that my back was so bad I could not even walk.
Overnight it went from loss of flexibility and discomfort to agonizing pain and basically being crippled. I looked like an eighty year old man with scoliosis. I went from 6'1" to about 5'0" just from being hunched over. Couldn't sleep. Did an MRI and found two herniated discs. They put me on narcotics and put me in physical therapy.
Now after four months of therapy and going through withdraw from painkillers I am just starting to go back into jiu jitsu and only in a limited capacity. The moral of the story, you're never too young to get injured! You're not invincible. I wish so much that I had taken more action sooner. I was foolish. Learn from my mistake. Get chronic pain checked out. Train safe.
