I'm not sure what inflamed would look like.

Ok,
Those look like normal blood vessels to me.
I've had many fish with clear and white or translucent fins and you
can see their blood vessels clearly.
It's time to be alarmed when an entire area or section becomes
inflamed and they all fill with extra blood. This looks more like a
bloody patch from a side view, but your fish looks completely normal
to me. Notice the top and bottom vessels are symetrical. Those vessels
are a little larger than the others, so you would naturally see more
red from the added blood running through.
I had a male Betta with clear fins once. When I would do a water
change on his tank, he'd get a bit stressed and you could see how red
his fins got from the high blood pressure. = o (poor guy did not like
water changes.) When he settled down, his fins lost the red road map
look and were back to clear.

Thanks. This is pretty much the consensus from the various places I've
asked but I just wanted to check.
