Flying from ZZZ to ZZZ1. No service due to turbulence. The forward lav was locked so the A and D [flight attendants] came to back to use the lav towards the end of flight. They noticed strange smell in the aft right lav. We all put our heads in to smell it and try to determine the cause. As we were deplaning we told Captain and he called Supervisor down and advised us to follow procedure for air quality. We all experienced different symptoms. I felt light headed; headache; and confusion. We went to Supervisor's office and called Global Health. We then went to the emergency room and had blood drawn; vitals taken; and put on oxygen for long time. My blood work came back at level 3 for carbon monoxide; which is high. We then were cleared from the emergency room and went to hotel for the night. No more information.
During descent at 18;000 ft. the A Flight Attendant and the D Flight Attendant went to the back to use the lav because the front lav is inop. Immediately after entering the aft galley area we smelled a strange odor. Both the A and D used a lav and came out separately complaining of a strong; strange and unusual smell inside the aft left and aft right lav. It smelled electrical/ chemical and like something could have been melting / burning. It was an acrid smell. It was very strong and left the A with a headache and upset stomach; and confusion just from using the lav and breathing it for a few minutes. We inspected all 3 lavs for a source of the smell and didn't find anything unusual. Told the pilots when we blocked in.Put on oxygen immediately if I ever have a similar event. Go to the hospital right away not hours later.
