|Can i speak to Huey please?|
A common question is "what's the difference between the expressions 'to be sick' and 'to feel sick'?" Well to be sick is to vomit, spew, puke, barf, throw up, or talk to Huey on the big white telephone. Yes i have heard this one used!
To feel sick has 2 clear meanings. If you feel sick then you feel nauseous, such as if you're having cardiac chest pain, have just sniffed dog poo, have travel or sea sickness (nausea comes from the Greek 'naus' = 'ship'). So you could potentially be about to vomit, which may or may not actually happen.
On the other hand, a patient may say that they feel sick to indicate that they feel generally ill or unwell, so they could have a cold, a headache or non specific symptoms such as fatigue. The most important point here is that if a patient says "i feel sick", then you should ask them to be more specific about the symptoms they have.
