Longer Waiting Times at City Care Centre

I am reliably informed that there is a 3 week waiting period to have an ultra-sound procedure at the City Care Centre, for those who may be in severe pain, just to get this done is now taking a very long time, the surgeries are well aware of the wait times, and say they can not influence ‘NHS’ waiting times.
I checked with a private health care provider who can give the same procedure in around 3 days….if you want to pay privately.
