On Saturday morning, the former Bachelorette, 31, shared a series of posts on her Instagram Story explaining her current health situation after she previously appeared to be hooked up to an IV and under a hospital blanket in a post shared on social media earlier this week. Addressing fans as she spoke directly through her camera, Adams began her lengthy message by first explaining that she is "finally feeling somewhat decent," before she shared more details about her medical ordeal. Noting that her current situation has nothing to do with her recent participation in the New York City marathon alongside fiancé Zac Clark, Adams said, "I feel amazing post-marathon, I feel like I've recovered quite well." The Bachelorette's Tayshia Adams Appears to Post from Hospital Bed: 'What a Day' "Monday and Tuesday was really the bulk of my pain from the marathon, but on Wednesday I was wearing heels, and truthfully, I was feeling great," she added. "... But then, that night, I had gone to bed, and I was, like, tossing and turning all night because of stomach pain." Tayshia Adams/Instagram Prefacing that she had experienced that pain "a couple of days prior" — but it was "nothing substantial" — The Bachelorette co-host then noted that by the time the morning came around she "couldn't even sit up straight because I was in so much pain." After rushing to the doctor, the reality star said she was suggested to go to the ER, where she underwent medical tests. Those exams, Adams said, ruled out issues surrounding her appendix and kidney stones, among others, but determined she had "a really bad kidney infection."

She told her followers that she "has medication" and has been "laying low," just staying in bed as she is still experiencing issues. "It's getting better, [there's] a tad bit of pain, but [it] just feels not right quite yet," she continued. "But this morning, thankfully, I'm on the up and up."

"I do not drink water, like, at all," she said. "And it's really bad, especially after a marathon, so that maybe could've been the effect that it may have had on this whole thing. But other than that, it's really just me." Zac Clark Praises Fiancée Tayshia Adams' 'Courage' After Finishing N.Y.C.
