The 22-year-old said that she and her team have discovered a potential cause for her recent struggles with injuries, which makes it more difficult for her to recover.
"Numerous scans, in and out of a moon boot, not able to walk, some days unable to even put any weight through that foot, and all the while being completely unclear on why I had such an atypical Achilles tendinitis.
"That was now 8.5 weeks ago, and we've only just come across a potential cause, which possibly has been present in some or all of the injuries I've had in the past 3 years. We think I might have a genetic disorder that causes autoimmune inflammation, particularly affecting tendons.
"Essentially this means over time microtrauma causes my immune system to go into overdrive and set off an inflammatory process in the affected area."
She said it has been "difficult to cope" at times, but is now in a better state of mind and is looking forward to working towards next year's Olympics.
"I've been continually challenged this year, and at times it's been difficult to cope, but the GOOD NEWS is I've started the medication for this condition and I'm finally feeling my positive self again
"I might not be ready to compete over the New Zealand summer, but all going well I'll be fit to qualify and build into Tokyo.
"It's going to be far from the ideal build up to an Olympics but after a year off I'm bloody ready for the challenge. There is a lot more I want to share but that's more than enough for one post.
"Please ask ANY QUESTIONS, I want to share my road to Tokyo with you all. Also, thank you all for sticking with me through these tough times, and a big thank you to my team and everyone else who has kept me afloat each time I've started to sink."
