Narrative: We pushed back from the gate and the A; C; K [Flight Attendants (FA)] all smelled stinky socks. As the push back continued the smell got stronger and the cabin crew started to have reactions and got really sick. We returned to the gate and deplaned passenger. The cabin crew sought medical attention. I was admitted to the hospital for further testing of my reactions to the fumes.I armed my doors and we pushed back from the gate. I walked to the front galley. We all smelled a dirty sock smell. I got into position to do the safety demonstration at row 8; I was the K Flight Attendant. During push back from the gate the dirty sock smell got stronger and my throat started burning and I was coughing a bit; which prior to push back I had not experienced. Before finishing the safety demo; the C and I walked to the front of the aircraft and asked the A if she was experiencing any reactions; she said yes. She then called the B FA and told him what was happening. We decided to finish the demo; as K I walk from row 8 to 16 performing the demo. My reactions got worse and I was hearing passengers coughing. I realized we were having a fume event and immediately went to the front of the aircraft and told the C and A and to call the captain to let him know. We returned to the gate and I walked to doors 3L/R to disarm. While I was waiting for all call I started feeling nauseous and dizzy. I heard more passengers coughing; a little boy in particular in 19C was coughing uncontrollably. The A made the all call announcement; while on the phone I told her more passengers were coughing and I didn't feel well from the fumes and we needed to deplane. I went to the front of the aircraft doors 1L/R to get some fresh as we were deplaning. By then I was dizzy and shaking inside; my heart was racing; and had a terrible headache. I immediately 24/7 daily ops and they answered the phone. I told them we were having a fume event and asked what the procedures were. He told me he had to talk with someone and he would call me back.We walked up the jet way into the terminal and the captain took a report from the cabin crew and then left. My reactions seem to get worse by the minute. We decided to go to baggage claim where we could catch transportation. They called the A back and told her he had transportation for us and they would be there in 20 min. We all were so sick we decided to take a taxi to the nearest hospital. While in the ER I started having chest pains and they admitted me for more testing. While I was in the hospital I started having tremors. They started in my abdomen and right foot. At one point my whole body was tremoring. My chest pains got worse. The testing performed came back abnormal and the Cardiologist ordered a heart catheterization. I was released.
