Swelling In Fingertips After Shoveling Snow Sometimes My Fingertips Get Really Turgid?

Sometimes my fingertips get really turgid? - swelling in fingertips after shoveling snow

They feel as if they were full of blood, which was visibly swollen and they feel really strong.
Did you this has happened, you know why?
Seems to occur sometimes when I go for a long time, and this morning it happened after I shovel the snow on my car and driveway, so I think it has to have something with my finger, my heart makes the need more exercise and exaggerated.
