In the UK, if you're considering a career change from public health to medicine, there are a few things to consider. A career in medicine requires a great deal of dedication and commitment, so you need to make sure that you're up for the challenge. You'll also need to be aware of the financial implications of switching careers, as you may need to pay for further qualifications or training. On the flip side, a career in medicine can be incredibly rewarding, both financially and emotionally. If you have the dedication, passion, and financial means to make the switch, it could be a great move for your career. Ultimately, it's up to you to decide whether returning to medicine is the right choice for you.
