I am suffering from severe abdominal pain most of it is in the lower right quadrant! I was in the emergency room yesterday and they did a CT scan and pretty much diagnosed me with colitis and also have kidney stones! I ve had two days of antibiotics on board Plus mild pain medicine! I have been suffering all day with the pain getting worse by the hour? it hurts so bad even when I was walking it felt like gravity your it hurts so bad even when I was walking it felt like gravity made it worse? Even coughing or laughing hurt really bad! I m not sure what to do but if it was or is appendicitis that they didn t detect at the hospital how much longer should I try to cope with the pain? I am nauseous most of the time but I m not vomiting anymore and when I urinate, it doesn t hurt but at the end of your name I feel a lot of pressure? I m not sure what to do? I just know that I m in an excruciating amount of pain!!
