TikToker describes excruciating contractions after she got an IUD inserted

“Smallwood said the nurse told her she could experience some cramping but that it would ease after about 10 minutes. However, the pain got so bad, Smallwood said she started vomiting and passed out. That's when "all hell broke loose," she said, and her arms and legs went numb.

"Then I start to feel something that I've only ever heard explained in movies," she said. "I don't even know how I knew what it was, but I knew that I was having contractions."

Finally, a doctor came in and inspected Smallwood, she said and decided to remove the IUD immediately.

"So she does an emergency extraction," Smallwood said. "It had gotten placed on a nerve."

Smallwood's video was shared by doctor and TikToker Dr. Kunal Sood, who has 1.7 million followers. He said the story highlighted how it's "important to take women's pain seriously."

Extreme cramping is caused by uterine contractions and is a known side effect

IUDs come in two types: hormonal, which release chemicals into the body to prevent pregnancy, and copper, which makes the womb an inhospitable environment for a fetus.

Dr. Yaa Oheema, a physician based in London, told Insider it's unlikely that someone's body would literally go into labor from hitting a nerve, because the type of nerves in the uterus "wouldn't cause symptoms like that." But there is no way to know for sure.

Intense cramping can be a side effect of getting an IUD fitted. It's hard to predict who this will happen to, she said.”
