"My hands are numb." Kim Kardashian shares health scare on the season return on KUWTK.

Even though the last season of Keeping Up With The Kardashians ended approximately six hours ago, the Kardashian/Jenner clan are already back with a new season and we need to ask: When do they sleep?

But whatever, we’re endlessly grateful to their decision to forego a vital human function because DRAMA and GOSSIP.

The first episode of season 17 (yeah… the Kardashians really have been on our screens that long) premiered last night and it certainly delivered. There was a continuation of that whole Khloe Kardashian/Tristan Thompson/Jordyn Woods clusterf*ck, because duh, but there was also an intense moment where Kim K had a health scare.

After experiencing worrying symptoms, Kim took a trip to the doctor. Post continues below video.

In clips from the season premiere, Khloe complained about how she didn’t want Tristan to attend their daughter True’s first birthday on account of that whole ‘cheating with Kylie Jenner’s best friend’ thing. Fair enough.

But afterwards, Kim complained about waking up with swollen hands.

“I’ve been feeling so tired, so nauseous and my hands are really getting swollen,” she said. “I feel like I literally am falling apart. My hands are numb.”

Kim suspected she could have rheumatoid arthritis or anxiety from expecting her fourth child, Psalm West, so decided to go see a doctor for blood tests and a professional opinion.

While waiting for the results, Kim opened up about her fears: "I have a baby on the way, I have law school. It just can really scare you when you start thinking about how much this is going to change my life".

At the end of the episode, her doctor called her to say she had tested positive for rheumatoid arthritis and lupus antibodies. The doctor explained that along with her joint swelling, she could also have fevers, rashes, mouth sores and fatigue.

Her doctor advised that false positive results for lupus are possible, but ordered Kim for a follow-up visit to undergo further tests.

The end of the episode saw an emotional Kim "freaking out" about the possible diagnosis.

"You know, you really do get in your head and think about the worst possible things that can happen. So for the next few days, it’s going to really be hell: Wondering what I have, what’s going on and how to fix this."

Rheumatoid arthritis is a chronic inflammatory disorder affecting many joints, including those in the hands and feet, and lupus is an autoimmune disease in which the body's immune system attacks normal, healthy tissue.

Neither have cures, but symptoms can be managed with treatments and medication.

Kim has shared her health issues with viewers of the show before, including her skin condition psoriasis, and her difficult pregnancies with preeclampsia and placenta accreta, which led her to use surrogates for her third and fourth children.

Presumably, we'll find out the results of Kim's additional medical tests on a future episode.
