Hi one day I was suprised by a lower back pain right above the cheeks. I took pain killers and it disappeared but suddenly I started waking up to urinate frequently. Almost every 2 hours. The urine is bubbly and a dark color. This stopped but now have a abdominal pain it started from the centre of my body and now has gone down to the lower right side. I decided to go to work with this pain and now am in bed with a fever and just vomited and the pain has dulled down but is still there any help
