when my son recently had tonsillitis, we had already seen a GP and therefore had a diagnosis, but as there was no improvement, I rang NHS Direct for advice - this was my experience: When my call was answered, firstly I was unable to ascertain whether I was speaking to a male or female operator as I am fairly sure English was not their first language, the person obviously had a check list procedure with no flexibility to enable me to say that we had already seen a GP, the operator checked my 'phone number at least three times during the call and kept going over the information I had already supplied, finally they said as they weren't busy I could be put through to a nurse straight away. When I spoke to the nurse, she was great, I knew she understood what the situation was and she, after asking a few more pertinent questions, was able to offer me excellent advice, it was just a shame that the experience was somewhat marred by the useless operator beforehand.
Yes I had been on AB to ask about it before phoning NHS Direct mainly for other points of view and a little peace of mind that I wasn't overreacting unnecessarily.
