Was wondering if anyone knew what I have. I've been getting sick almost every two hours since last night at 4am, it is now 9pm. I have a temperature and pain in my lower back. I'm 19, and suffer from reflux but I take a tablet to control it twice a day. I'm experiencing horrendous pain in my stomach all day, not even easing after I puke. Does anyone know what this could be other than a bug ?? Help please asap
