Hi there,
I'm also a mature student (23. 24 by the time of uni) I'm starting an access course in September then hopefully going to progress on to uni next year to study Physiotherapy! I've currently been getting placements within physiotherapist settings etc which is really helpful and gives you a good insight to the profession and obviously will boost your chances of getting an interview as most if not all universities require some form of work experience!
Universities I'm looking at are Liverpool, Brunel, Southampton, Plymouth, Huddersfield, Oxford Brookes, Keele, Cumbria, Leeds Met, MMU, Teeside. Quite a few as you can see! Just need to narrow them down.
I have no concerns really, though I know it's going to be hard work as the course is very demanding. But hard work pays off right? I don't think your issue will be a problem to be fair but its probably worth reading what the course entails on the university website or just giving the uni a call and enquire.
Good luck with your application when it's time to apply!
