Dealing with the NHS is not necessarily less hassle, just a different kind of hassle if you have ongoing health issues. Not that I'm complaining.
Basically the deal is that there is a proposal to stop people who have used the NHS illegally and failed to pay from coming back to do so again. They mean that if someone came in on a visitor visa/visa waiver and got non-emergent care over £1000 but didn't pay for it, then it will have to be paid back for that person to obtain permission to come back. It's not the first time it's been proposed, and honestly no one can tell you who all will ultimately be affected until it moves forward. Just keep an eye on the forums and as more information is released someone will definitely post some clarifications here, probably Transpondia (although there are other people here very good at clarifying this stuff as it comes out.)
Don't let it worry you right now, and definitely don't believe what newsources are putting out...even the most reputable sources make their money from ads so they use evocative phrasing and misleading quotes. It's news, not necessarily information. Good luck with your studies.
