pain is a psychological condition. the medication commonly used for it is certain painkillers, antiemetic for vomiting
and sedatives for the mood elevation of the patient. the sedatives also have the effect of the hypnotics i.e. they induce sleep to stablise the patients mental activity by stabilizing the neurotransmitters
. hangouts after such medications is common for a day or 2. and subsides with time. however if you avoid food and fluid intake the effects may persist for longer time. so you dont have to worry and just maintain your food intake and the effects will subside within a day or 2. however do check your blood pressure. if its normal then there is nothing to worry about.
