As long as you've established UK residency, i.e. not a visitor, you're entitled to NHS. Doesn't matter if you're here to work, or study, etc. I think you'll be able to get all that and more with the NHS. They're a bit on the slow side for getting labs done and everything, so make sure you register with a GP right away and explain the whole situation. They should be able to get you sorted out and tell you what you need. I imagine that if you can bring copies of your medical records with you, that will be a big help. NHS, while very slow, is pretty decent too, and its nice that anyone,regardless of age, health condition, income, race, gender, etc, can get treated.
