Narrative:

Upon descent the cabin began to fill with a strong odor of sour laundry. The air became very thick and hard for me to breathe even to the point of saying I feel like I can't breathe and began to use my sweater to breathe in. I was flight attendant (flight attendant) D and also noticed that passengers in the back were agitated and closing their air vent and making complaints. When passengers deplaned the D flight attendant approached the captain to explain the severity and effects we were beginning to feel from this and he proceeded to write it up. We all exited the aircraft to try to get some fresh air as it was uncomfortable in the cabin. Individually we called the [medical services] line and were sent to urgent care which in turn sent us to the hospital. I was treated with oxygen and gave 3 blood samples to find out my carbon monoxide was elevated to a 3.2. The last blood sample was what the company ordered and I don't know what that was for. I was released with the recommendation not to fly until [a week later]. There were issues with crew services not knowing where we were even though our base supervisor was in contact with them about our incident. After difficulty with crew services that was handled by flight attendant a and flight attendant B we made it to the airport [for] the return flight. I have heard this particular [aircraft] has had a history of this odor and to prevent this; proper maintenance should be completed before the aircraft is put back into service.
