Had surgery to burr forehead, temple and vertex, need some advice please.

I had surgery on the 17th of August. The DR burred down the forehead, right temple (it was protruding a bit) did some aesthetic balancing on the skull(had lumps and bumps) n reduced some of the vertex too! Recovery has been ok pain wise, but i have quite bad fluid retention on my forehead (nowhere else) it feels as though i have a few dents in my forehead, is this normal to feel that way or should i be concerned that i actually have dents? any suggestions to help reduce the fluid either?
