I went to the ER this morning with my 15 year old daughter. She woke up this morning with bad pain in her stomach and lower back, she passed out completely for about a minute or so, we rushed her to the ER. She had low blood pressure of 86 over 60 and pulse was 69. She was very pale, eyes rolled back when she passed out. At the hospital they checked her blood sugar which was 89, did a urine test, EKG, and ultrasound. Said it wasn t her appendix so they sent her home. I am still concerned because I do not know what caused this to happen. She is still having pain, she is still cold, and started having diarrea now and her blood pressure now is 93 over 64 any ideas what is wrong wit her or what I should be looking for.
