Hi, My name is Wendy and I am a 59 yr. old female who 2 wks. ago had gone into the ER I my area with strange pain in my right lower side, below rib cage - well, 3 hrs. later (after blood and urine test) the ER Dr. came in and said; I had a kidney infection, prescribed Sulfa drugs for 10 days and sent me on my way. I was told to follow up with my regular Primary Care Dr. which I was gonna but cancelled cause I was feeling better. Now, the pain has returned (not as severe as it was) and I called it strange because it only occurs when I move certain ways, i.e. twist my waist or press against my side, its tender. I know that I ll probably have to call my Doc but I wondered about the possibility of kidney stones and symptoms of and how do they test for. I m not trying to borrow problems but I feel like my body is trying to tell me something, an you advise please? Thank-you! I m sorry to have bothered you I didn t realize there was a charge for this advice - I live on a fixed income and have Medicaid and Medicare (disabled). I ll just have to call my Dr.
