Before I went to the ER it would switch in pain, sometimes it would go to the right. But I did alot of walking today so it kindof hurts and I didnt get to wear briefs which is probably why. Is this anything I need to be worried about? What happens if the pain doesn't go away, than should I be worried? Cause I have had this dull ache for almost a month it just started more symptoms like lower abdominal pain and flank pain and lower back pain but after antibiotics that has gone away. They tested my urine for kidney stones as well and it didn't say anything on my discharge papers so am I okay kidney wise?
