[Closed] Flat spot on car rim, is it unsafe?

Noticed this a few days ago. Reckon its bad enough to need checking out somewhere? It doesn't seem to be causing pressure loss or deforming the tyre, but I dont know enough about cars to say! Where should I take it, a dedicated tyre shop, and is this sort of thing fixable without having to resort to buying a new wheel? This is the second time I've damaged a rim due to our poorly maintained roads and big potholes - the last one was a write off as it cracked the inside :\
