"Shocking rudeness of paramedics"

My face swollen double the size and i was rushed to hospital. The paramedics that took me were amazing, but when i arrived my paramedics that that took me started speaking to another paramedic, at this stage my throat was swelling and i was finding it very hard to swollen and short of breath, i was so worried it was going to get tighter that i used my phone to reflect my face and throat on it, when i did this the other paramedic that was speaking to mine said in an aggressive mocking insulting way and i qoute "youre in ae and youre taking selfies!" then they walked off with another person laughing and saying "lets take a selfie" mocking me again! I suffer anxiety and this made me want to leave straight away and hide, but the doctor straight away n took an xray and injected me with antibiotics. I would like to take this matter further or ill seek further advice from citizen advice. Will say my name privately
