Given one of the primary justifications for not leaving the EU was to retain access to unlimited cheap labor for the NHS, it isn't easy to blame low medical worker wages on Brexit. If you want medical staff to make more money, removing their primary source of competition is a quick way to do that.

In practice of course Brexit has done no such thing as the immigration rules in the UK are still optimized for mass immigration, as the Conservatives are so much not xenophobic that they prefer to enrage their own voter base than restrict immigration by even small amounts.

As for healthcare spending, the massive jump in NHS spending during the pandemic more than consumed the former EU contributions. The EU funds did indeed go to the NHS and then a lot more on top. If the UK was still paying in, then inflation would be even worse.
