"Terrible and concerning"

I brought my partner to the Leicester Royal Infirmary under the advice of his doctor. His doctor had explained that whilst it was likely that his chest pain was muscular, they could not be 100% sure and the doctor did not have the relevant resource to ensure it was not any more serious as the symptoms suggested possible PE or pericarditis. The doctor gave us a printout of their information and highlighted the information they had added regarding their concerns ect and told us to go to the Royal. After having an ECG at the hospital he saw a doctor who seemed confused as to why he had come in. We explained and gave the doctor the information from the GP but they still did not want to help. We persuaded the doctor to transfer my partner to Emergency Department and waited to be taken over. We hate this system anyway due to previous bad experiences but knew it's normally quick to be transferred and then a 6 hour wait in A&E. However we waited for over an hour and still had not left the walk in. I approached the desk and was told there are people out there dying and my partner is still walking and talking therefore it could be hours to be transferred as he was not priority. So we continued to wait, then my partner became concerned as he was in a great deal of pain, had not been offered pain relief and had not been transferred. So we both approached the desk where they repeated themselves, gave no quality explanation and told us we would be better finding another another hospital. We asked for the paperwork back but it had been transferred to A&E and they could not retrieve it. So we left and went to Kettering A&E. The service was fantastic and the staff were great, they diagnosed him with Pericarditis, a heart problem and gave him the relevant treatment. The most concerning part was that Kettering spotted this mainly from his ECG which was interesting as Leicester had also done an ECG but failed to spot this. Overall I think LRI is getting worse and to be honest I don't trust them. Disappointed is not the word.
