Having just started walking again after breaking my own foot (calcaneus) and being treated by the NHS…
It may well be the case that the treatment provided has been as good as it can be, and that what is lacking is the fluffy stuff. All the appointments I had were in overcrowded clinics where the doctor was hugely overstretched. After feeling a bit fobbed off with each appointment to begin with, I found that by writing down a few questions and concerns I had, and specifically asking the doctor to go through them with me, I came away feeling a lot happier.
For a broken foot, the best thing to do is generally just to rest it until the bones are healed, which can take a long time and is pretty frustrating. I was also given a boot rather than a cast – this is becoming common practice since it means that you can take it off to scratch and wash, and is generally considered much better than a cast (I thought so!).
Complain if you like, but from my experience I would suggest a simple plea for a bit of a reassuring chat first. I agree that the reassuring chat should be part of giving proper care, but NHS clinics are so overstretched that this often gets missed out just so that everybody can be seen eventually. Doctors are overworked and are prioritising the important treatment rather than making each person feel happy and loved. Not ideal but best that can be done with limited resources.
