Let us consider a bounded, Borel function $F\colon \mathbb R^d  \to \mathbb R^d$. Assume it satisfies the following 
[Osgood-like][1] condition: 
$$\tag{O}
\boxed{\langle F(x) - F(y), x-y \rangle \le \Vert x-y \Vert \rho( \Vert x-y \Vert)} \qquad \forall x,y \in \mathbb R^d,
$$
where $\rho \colon [0,1) \to \mathbb [0,+\infty) $ is an Osgood modulus of continuity, i.e. a continuous, non-decreasing function with $\rho(0)=0$ and 
$$
\int_0^1 \frac{1}{\rho(s)} \, ds = +\infty. 
$$

> **Q**. Is it true that $F$ is continuous? Or, more precisely, is it true that $F$ is equivalent, up to null sets, to a continuous function?

Beside the link above, something (mildly) related can also be found [here][2].
Thanks.
