Severe abdominal pain!
I am a 21-year-old female and for the past few days, beginning in the early morning, I have been experiencing severe abdominal pain and nausea for hours that constantly wakes me up. Yesterday, between 5:30 am and 8:30 am, I vomited six times! I have experienced abdominal pain at night throughout my life, but nothing quite so severe. Furthermore, during the day, my back has been hurting and I have been experiencing cramping. My period is typically a 33 day cycle and is now a week late. (I am not sexually active.)
This year has been very high stress, but I have not had this issue until now. I am entering the final three weeks of school for the term and I do not have time for pain. Does anyone know what could be causing this? With limited time and finances, I am not really willing to make a doctor appointment to have someone tell me that there is nothing wrong with me.
