my wife doubled up in pain 2 days ago, i rushed her to hospital, the doctor said she had colic pain, i have never seen her cry even giving birth to our daughter!! he scanned her to check the kidney and stated she had sands, gave her a painkiller jab and an antibiotic jab and sent her home with painkillers and a week antiobitic course. She was ok until today now she just had very sharp she said something was moving down towards her uterus...why is this happening and why when she is the healthiest person i know, (drinks loads of water, all the right foods).
