"Complain"

I have done kidney operation recently.i have pain again i called ambulance first i waited 3 hours for ambulance after that they leave me in emergency.i checked by nurse and she asked urine simple an blood sample i gave to them.but she told me that u have to wait in waiting room for 2 hours.i requested that i am not able to sit but they refused saying that we have no bed available.unfortunately i saw a lot of spare bed.the way they treat me i am not satisfied.i took tramadol which make me sleepy.i can't explain my condition.
