It would be helpful to know what kind of roles you are have been in and what makes you hate it?
I wouldn't personally go in to aesthetics, the whole industry worries me..you have to pay someone to prescribe your fillers and they haven't met the pt. Then what if they go in to anaphylaxis? Do you have adrenaline on site? Wouldn't like to be the sole trained person dealing with an anaphylaxis. One of the nurses I work with did it successfully for years but has stopped now due to reading about the potential for necrosis if she hit a blood vessel at all.
I looked into microsuction, I think it could be great. If you got trained and also got trained in cutting toenails and went round care homes I think it would make a massive difference to people's quality of life.
Nursing education? You'd need to aim towards your masters but could be fairly satisfying. Or you could go to a college to teach the svq in heslthcare? Alternatively look at nearby medical schools, sometimes they advertise for nurses as clinical skills tutors.
Occupational health? I almost took a job for British transport police WFH mostly with clinics for new starts testing fitness. It was incredibly generous.
Working for a drugs company? I have seen quite a few jobs for contvatec for a stoma nurse, I think a lot of it would be more sales led to those who prescribe the products but you would also be the expert in those products. I bloody love a stoma so I have considered it.
Within the NHS....
Research, education (clinical educator?), frailty practioner/complex discharge nurse (in our Trust do full assessment and deal with SW ref/family/PT/OT...band 7 and much less clinical but not management), OP clinics?
