Aircraft
We were on a maintenance delay at the gate on [date] after we arrived [at ZZZ]. All 3 flight attendants were in the last rows of the aircraft. Without warning we started experiencing light-headedness; dizziness. We had trouble exiting the aircraft due to extreme heaviness in legs. Airport EMT's were called. All 3 flight attendants were taken to the ER in ambulances. We all received treatment. The A [Flight Attendant] and I received IV's. Doctor's diagnosis was an inhalation event of unknown origin. When we were discharged from the ER we were sent to the hotel. We were now at 7 hours; 30 min crew rest. Our board shows a 14 hour overnight in ZZZ. They used our block in time instead of factoring in all the other events. We felt pressured to continue on with our regularly scheduled day. We should have called in fatigue; [company] management makes any flight attendant who calls in fatigue attend a fact finding meeting. This is clearly to intimidate flight attendants to not ever use a fatigue call. No flight crew should ever be expected to fly their regular flights after such a stressful medical event. Punitive measures by management to discourage flight attendants from calling in fatigue should be immediately discontinued. Possibly if 1 or 2 people only from the [Operations Center] handling these crew medical events would help eliminate any misunderstanding about crew rest legalities.
B737-800 Flight Attendant reported health issues during maintenance delay resulting in entire Flight Attendant crew treated by medical doctor for inhalation of unknown fumes.
