Last night, right after work, I started having severe pain in my lower back/right side. I had a terrible time sleeping (cold not get comfortable in any position...hurt worse to lay on my left side than on my right...lying on the left cause my right side to hurt worse.) and woke at 2am in severe pain. My husband gave me 2 advil PM and it eased the pain enough to allow me to sleep in a propped up position. the pain is not nearly as intense, but is still there all day today. I have not been urinating as much as normal, but figured it was because I haven't been drinking as much as I normally do. Ever since the pain started, there has been a small amount of blood when I wipe, but I can't tell if it is coming from the urine or from...other locations. My side still feels swollen. sometimes the pain is eased by rubbing the area, or passing a little gas. Are these signs of something serious...should I be rushing to the ER or waiting to see if it eases? Does it sound like kidneys or ovaries or intestinal?
