Hi, I m a 15 year old girl and about a month ago i woke up in the middle of the night with severe lower abdominal pain to the point where i couldn t move without being in serious pain. As well i had a fever and chills and had vomited about three times. I went to the hospital and they did an ultrasound but said they couldn t get a clear enough look at my appendix to see if it was a appendicitis , and the pain had lessened a bit so they said to go home and monitor it. After a week the pain had almost completely gone away with just a hint of dull pain in that area, and that still hasn t gone away as well every once in awhile i will get throbbing pain in that area where it is felt when breathing , but it will go away in usually ten minutes, just wondering if you had any ideas of what it could be or if it is anything to worry about? Thanks.
