Hey,
Sorry you're not feeling your best! Let me start by telling you about my own experience of this; I was 18, just getting into tramp again after a few years break. I landed squarely on my head, hyper extending my back and badly winding myself. None of the coaches were looking my way, and a friend who was spotting for me lifted me off the tramp, and I quietly (feeling rather stupid for landing on my head) lay flat out on some mats for a while. My back was hurting a lot but I didn't say anything. I think I might have even had a couple more turns on the tramp before I went home.
Two days later my back was still hurting but I went back to training anyway. I basically suffered through the pain for the next 3 months, at which point I mentioned to my physiotherapist my symptoms and what had happened. She was very concerned and arranged an MRI, which showed a break in the facet joint (the bits of your vertebrae that join them all up) which I'd been walking around with for the past 3 months. I was (thankfully, and very luckily) fine, and recovered with no issues, however it could have been much, much work.
So now, on to you. TELL SOMEONE. Seriously, I know what it's like, being out fbecause of injuries sucks, the recovery process in general sucks, making people worried because you are hurt sucks. What sucks more though is having chronic pain for the rest of your life, which would cause a whole lot more worry and pain! Most likely it's nothing and can be easily fixed, but you won't know that until you speak to someone about it.
