The government needs to be very clear on what it means by "long covid". The potential for this to be a malingerers' paradise is huge. When UC came in 800,000 went off the sick list. We can't afford to load them back on. Harsh but true. We are making a rod for our own backs.
ME has some evidence on MRI ut yes we cannot base our welfare system on subjective reporting. It's unreasonable and money spent there doesnt get to public services. It has a cost on providing decent health care long term.
