I m having really bad pain on the right side of my stomach more towards the top but kindve in the middle, I went to the ER yesterday night because of the pain and they did an ultrasound and urine test but they said everything was okay and that i was fine && for me to rest until I visit my regular doctor and they put me on a diet with foods that I should and shouldn t eat until my next visit with my doctor && prescribed me Zantac and acetaminophen, today the pain is worse than yesterday I ve been lying in the bed all day (resting like I was told) && Everytime I move the upper part of my body the pain gets worse, (sitting up, turning, lying on my stomach and sides, any type of movement that involves my my upper part of my body from the waist up, etc...) && I ve been having lower back pain and nausea along with the abdomen pain ... What should be my next step ?
