Ok, so panic dies down.. I'm not going to be paraplegic. It's only a slipped disc. I say 'only' but it's still bloody painful. And surely it shouldn't happen to a 24 year old! At least not on a regular basis. So, once I figured it out, I massaged my spine and since then I've been able to walk, carry stuff etc.. still not cured but I'm mobile. Hurrah!
To celebrate, I went to the beach. Instead of lying at home feeling sorry for myself, I lay on the beach feeling sorry for all the beached whales aka size 40+ tourists rolling about on the beach.
I just hope I can start running again soon or I'll look like them before long.
