my daughter aged 3 1/4 yrs has been suffering from leg pains for a long time.blood and urine test have been done on doctores prescription.the doctor said it could be due to calcium and iron deficiences and so ferrocalcium tonic was prescribed.stil these episodes of leg pains do occur mostly in the night.when these pains are severe i give 5ml of tastymol which gives some relief.is ther some way to avoid them completely?
