What exactly is nausea?

What's wrong with me? Abdominal pain, kidney pain, sudden intense nausea, hard to swallow, recurring UTI.?

• Ok, for the past few months, I've had recurrent low back pain in the kidney area, and I've felt bloated and uncomfortable. About 3 months ago, I had a UTI, my first one in years...then about 2 months ago, I starting getting pain in my right hip, which felt like I strained a muscle. Over the past week, the hip pain's more intense and it hurts to sneeze; I've gotten another UTI which hasn't been cured completely by Sulfatrim, and all of a sudden today, I came down with an intense feeling of nausea and coldness all in my stomach and esophagus, like it just washed over me really fast. All the while, I still have abdominal pain, cramps around my pelvis, and kidney pain. I went to the ER when the nausea hit and they just gave me Diavol and sent me home. Now, a couple hours after the wave of nausea, I feel slightly better, but my stomach still really hurts and my limbs feel pretty week, like all I want to do is lay down and sleep. Any thoughts of what this is? Oh, I will be seeing my doctor, I just wanted opinions.

  It sounds serious possibly. Shame doctors are so lazy and incompetent, for all the money they suck up. Try plugging your symptoms into some online symptom checker like http://symptoms.webmd.com/ and then try to get a doctor to follow up.
