Covid vaccination update

So i got it two days ago (i was a sore mf) the first day was a living hell i could not get comfortable at all or i felt nauseous af, the second day i spent the night at a friends house and i could move my arm up a bit but his dumb ass pushed into my arm and when i tell you i wanted to cry i mean it, so i poked his shot area and yea it didnt feel so nice... But today when i came home the shot hole was just and still is piercing, it healed up and i didnt touch it so i have zero idea why my shot hole is just doing what it is(/TДT)/
