So a week ago I went to the doctor with servere abdominal and lower back cramps. They said I had a bladder infection and gave me antibiotics to cure it. The lady said within 48 hours the antibiotics should have been working and I shouldn't be hurting anymore. Well I still hurt and it's been a week.. Seems like every time I get up and going for just a little bit the pain gets really bad. Now today I can barely keep down and food or fluids without feeling the need to throw up. Has anyone ever experienced this? If so ladies please help me!!!
