Hello
This sounds like a nail infection (paronychia or abscess) that is spreading.
Because there is pain, swelling, pus under the nail, and a black spot → you should see a doctor urgently.
🛑 It may need drainage and antibiotics.
What to do now: Do NOT squeeze or pop it again 🛑🛑Soak finger in warm salt water 10–15 min, 3–4 times daily
Keep it clean and dry Seek medical care as soon as possible
Go urgently if pain worsens, fever appears, or swelling spreads to the finger/hand.
Here i can only prescribe antibiotics
But you need abscess drainage also
Thus please consult your nearest doctor in person
Thank you Take care
