I was in the forward part of ac greeting passengers as A position. We had boarded about 6-10 passengers when I received a call from the FA in aft of cabin. She asked me to look in cabin to see if I saw a haze in the cabin and if I smelled an odor. I did see a haze in the cabin and I did smell an odor that smelled like burning plastic. The other FA called to the flight deck and asked the Captain or First Officer to come through and smell the odor. In the meantime the Captain looked in the log book and had seen a pattern of hydraulic fluid leaks being checked/fixed. He immediately had the passengers and crew members exit the aircraft as the fumes are very toxic. We deplaned and at the advice of the Captain had the paramedics come and take a look at us. We then went to another gate and flew to ZZZ1. We deplaned and got on another aircraft to go to ZZZ2. About 3-4 hours into the flight I started to notice that my lungs were burning as well as my throat burning and head was hurting. I told this to the other Flight Attendants in the back who had been on the aircraft with me with the noxious fumes earlier and they too indicated they had the exact same symptoms. When we arrived at the hotel; we called Global Lifeline / MedLink who advised us to seek immediate medical assistance. We went to the ER where we were evaluated and told to follow up with our doctor if we had any more issues.We have not confirmed what caused this to happen but it appears there could have been a leak of hydraulic fluid seeping into the cabin when the APU was turned on.
