Hard lines within hours after Restylane filler in tear troughs, my injector said it was normal —is it? (Photos)

I had Restylane in my tear troughs today. It was fine immediately after, but within hours, incredibly hard lines, where I assume the filler was placed, developed, and popped out, making it look very lump and uneven. I called the injector who said it was likely just swelling and the filler will "settle" over time, but this is so hard - it's not just one lump, it's like a continuous limp that runs in a line under both eyes. Is this normal?
