Narrative:

About 10+ mins after ascending I received a call from flight attendant 2 asking if I smelled anything out of the ordinary. I did. Initially; it was a very faint chemical-like smell. I got out of my jump seat (3L) and walked a few rows towards the forward part of the cabin and the smell was about the same. I then called the flight attendant 1 to share my observations. Flight attendant 1 was in communication with the flight deck. Afterwards; I went to the aft part of aircraft and the smell got stronger. Now; it was a chemical/car coolant leak smell. At one point; someone opened one of the lav doors in the aft; and the smell intensified. Some pax shared similar observations about the smell in the cabin. Shortly after; the captain came over the PA and informed pax that we were returning to ZZZ [departure airport] as a result of a cabin odor. While preparing for landing; I started feeling tingling in my legs. I returned to my jumpseat upon doing my compliance checks; and the tingling sensation increased. I also felt my thoughts get fogged. We landed; arrived at the gate; and deplaned. Emergency personnel and [manager on duty] were available to assist and guide us to get medical assistance. About 2 pax that felt ill received medical attention in the terminal. We requested to go to the hospital. [Manager on duty] coordinated our transportation to the hospital; guided and assisted us to our transportation. Once at the er; I got a headache; continued to feel tingling in my body; and my thoughts were fogged. My initial blood pressure reading was slightly elevated. My second reading was even higher. Please note that I don't have a history of high blood pressure. My carbon monoxide levels were measured and no co poisoning was detected. I was released from the er. (Before being released; my blood pressure reading was within normal range). It is currently [a few days after] and I have a headache; feel very tired; my arms and legs feel sore; and my thoughts are still fogged.
