Lumber puncture private

Hi new to all this im currently awaiting for a lumber puncture on the NHS not sure how long it takes anybody got a rough idea or is it a good idea to go private and if so how much is the cost please

Mine is booked for the 14 nov. Consultant put the request in on the 25 oct.

I don’t think the wait for lumber punctures is that long. It is the waits to see a neurologist that tend to be very long, because of the big shortage of consultants.
