7 days ago I had a sore finger thinking maybe ingrown fingernail or cut. Next day it was purple. I kept triple antibiotic oint. on it. It had a little puncture and when I squeezed the purple, a little blood and clear liq came out and most of the purple went away, Today the end of my finger is red and the side of my finger is white and its throbbing,,,,,,,,do I need to have it checked? I work in a pharmacy and my pharmacist suggested to get it checked
