"Short waiting time but mis-diagnosed"

I was seen very quickly (within 10 minutes) at Charing Cross A&E however, I was misdiagnosed with bursitis of the elbow which actually transpired to be severe cellulitis caused by infection. The doctor was very chatty but certainly dismissed my condition despite my communicating to her that I felt sure my arm was infected. She seemed to think the cut and insect bite on my arm and the fact that I had been abroad for two weeks were irrelevant! After a couple of days of deteriorating I went to a GP who prescribes two antibiotics and signed me off work for a week.
