preparation, some times it can result in sodium retention and water retention, but this effect is very minimal in normal person, to be concerned only in cardiac patients. your symptom of head pressure and thirst could be due to poison ivy , or due to fear, rarely due to prednisolone , it is not much serious condition to worry,
