As soon as I truly finished vomitting , I went straight to bed , and that 's when the pain started . I had pain on my left side and left abdomen . It was so severe I could n't move . I luckily fell asleep and did n't get out of bed until Elisabeth came into my room to check on me at 5 pm Saturday evening , a full 17 hours later . I had n't been able to get up to use the bathroom , to eat , or to even drink anything .
