Hi, my wife is currently suffering from kidney stones. She has been in dis comfort and went to a&e today.. She was discharged this afternoon. Tonight she went to bed, taking the following- diclofenac 50mg, co codamol 500mg and nitrofurantion 50mg. She got up to pass urine around half an hour ago and fainted, but came- to quite quickly. She is in bed now, talking but seems very tired and drowsy. Just wanted to know if this is normal and if not what action should be taken? Many thanks
