I'm on morphine, oxycodon & nitrous oxide to regulate it, as before the pain made me throw up & pass out — Cristian MJC (@CristianMJC) July 31, 2016

Updating followers with the above Instagram picture, he wrote: "So after years and years of intense swimming training and gym to aid that, I've developed serious Arthritis, and the shoulder of a 50 year old... lol. I know not that funny."

Saying that he's "pretty devastated", he continued: "Whether it's competing at the Nationals, the 5am starts, or the sacrifices I've made, it's been really rewarding and taught me a lot about commitment, self-discipline, and that whatever you put in, you get out.

"It's defo gonna be difficult coming to terms with the fact I'm unlikely to ever compete at the same level again or even reach my full potential, but I guess that's what happens when your shoulder keeps popping out every time you try to lift something..."

However, Cristian updated fans hours later to share some welcome good news on Twitter: "Getting sensation back in my arm, so that's good news! Very disoriented from all the drugs which are horrible, but the pain is easing."

"The physio came today and he reassured me it should improve! I think it's just a time thing right now," he also told a concerned Twitter follower.
