"My son being discharged too early"

My son wasnt feeling very well he had been falling down all the time. As he has heart failure he knew he was in serious trouble. He got to his doctors who then rang for an ambulance to take him to whiston hospital. A few hours later although still dragging his left leg and unable to use his left arm and hand he was discharged. As he lives on his own I was mortified. He didnt have a good weekend. He phoned his doctor three days later to ask how long it would be before he would be able to walk and use his arm and hand properly. The doctor couldnt believe he had been discharged. Its too late to rectify his treament but hopefully it doesnt happen to anyone else. To be fair the nurse who attended him was very concerned. She asked three different times was the doctor sure he could be discharged and was told he was fine now.
