What causes costochondritis? Is there anything that aggravates it (like exercise or diet), or is it possibly viral?

Costochondritis can be aggravated by any activity that involves stressing the structures of the front of the chest cage. It is generally best to minimize these activities until the inflammation of the rib and cartilage areas has subsided.
I am unaware of any particular diet causing worsening of costochondritis. On the contrary, it is known that fish oilscan have a degree of antiinflammation effect. Theoretically they could be of some benefit. This effect is probably minor, however.
