In the article, we give a presentation of the fundamental group of the complement to a curve $C$ in its "tubular" neighborhood in a normal surface $S$. The presentation is given in terms of the double weighted dual graph of a resolution of singularities of $C$ (and $S$)and it is a generalization of the presentation of the fundamental group of the complement to a normal singularity in its neighborhood given by Mumford in the case when the dual graph of resolution is a tree and all exceptional curves of the resolution are rational curves.
