(#5) Waves Of Nausea
Kelly's fear is palpable on page six:
I'm seriously nauseated now, feverish, and my pain has gotten worse. This isn't like how I felt after my last mission. This is much, much worse.
-
(#7) An Overwhelming Nausea From Gravity
Kelly contended with overwhelming nausea, also discussed on page six:
I'm also nauseated, though I haven't thrown up. I strip off my clothes and get into bed, relishing the feeling of sheets, the light pressure of the blanket over me, the fluff of the pillow under my head.

(#6) Muscles And Joints Feeling Prematurely Aged
Kelly wrote about his experience in the Sydney Morning Herald:
It's March 2016, and I've been back on Earth, after a year in space, for precisely 48 hours. I push back from the table and struggle to stand up, feeling like a very old man getting out of a recliner.

(#2) An Extremely High Risk Of Cancer
Kelly's cancer risk was significantly increased by the time he spent in space. According to The Globe and Mail:
During his months in space, Kelly had more than 30 times the exposure to radiation of a person on Earth – equivalent to about 10 chest X-rays a day.

(#4) A Rush Of Blood To The Legs
Kelly details the start of the leg episode with his challenges just trying to move:
I struggle to get up. Find the edge of the bed. Feet down. Sit up. Stand up. At every stage I feel like I'm fighting through quicksand. When I'm finally vertical, the pain in my legs is awful, and on top of that pain I feel a sensation that's even more alarming: it feels as though all the blood in my body is rushing to my legs, like the sensation of the blood rushing to your head when you do a handstand, but in reverse.

(#8) Problems With Vision
Even on his earlier, shorter missions, Kelly had experienced a small taste of what he would later experience more extensively after his longer trip in space. After an entire year in space, the previous health problems only magnified:
On my previous flight to the space station, a mission of 159 days, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained and shrank the walls of my heart. More troubling, I experienced problems with my vision, as many other astronauts had.

About This Tool
Scientists have been studying the effects of space travel on the human body. Researchers from multiple institutions in the United States conducted comparative studies on American astronaut Scott Kelly who after 340 days on the International Space Station and his twin brother Mark Kelly. They collected and analyzed the health conditions of the twins.
The study found that Scott Kelly's carotid arteries, retina, and gut microbes had changed. Most of these changes were restored within 6 months after returning to earth, but a small part is long-term potential damage. The random tool lists 13 things that happened after Scott Kelly got back from space.
