Health - lil bumps from iv use days ago? ok or bad?

[Donmeka]

at first SWIM thought it was an abscess but SWIM looked at pictures and it looks nothing like what SWIM has seen. it is barely painful sometimes not at all, if swim extends his arm all the way he feels slight pain. it isn't red at all no weird looking symptoms except a bump feels kinda like 2 next each other. SWIM just doesnt know if it can be serious or not.

SWIM had a similar situation on his other arm and it went away today is a little sore but there is no longer a bump. should swim put ice or warm pad and see if it goes away like his other arm or could swim ave an abscess? SWIM is a little afraid but has heard that an abscess is very painful and SWIM thinks it is just what happened from a missed shot and will go away given a couple more days. this experience has been enough of a bitch that SWIM will never try IV use again oh and his use is not at all besides the past week or so less than 1- total tries/experiences.
