Is it serious?

Superficial thrombophlebitis is typically more annoying than serious.

Usually, the blood clot clears and the inflammation dies down within a few weeks.

Most people with superficial thrombophlebitis are otherwise well. There shouldn't be any foul discharge or abscess, and it's normally just lumps under the skin rather than swelling of the whole calf. This may be painful, but it shouldn't prevent you walking reasonably well.
