My finger started to swell up around the nail a bit last night, and has dramatically increased over today. now the tip of the finger feels swollen. I poked it with a needle and initially a yellowish pus came out, but even when the pus came out it didn t deflate. I ve been soaking it in warm water for 30minutes, and the pain is less, but swelling still pretty bad. Do I need to find a doctor immediately (it would mean going to the ER at this time of night), or can I wait til morning?
