So about a week to 10 days ago, I missed part of a shot in the crook of my arm. I weas stupidly letting a friend inject me(never allow it anymore), so he pushed maybe 10 uTnits of liquid into the arm without hitting the vein, the needle slipped out. The area around it swelled up a bit and was painful . Over the past days, the pain has gone away, the reddness is also pretty much gone, but the bump is still there, its a hard lump thats about an inch in diameter. Is this an absess? since the pain is gone, will it eventually heal itself too? The only other time something similar happened was in the same arm, but further up the arm. In that case, it took the lump over a month to go away. I would like this gone sooner. Can anything be done to accelerate the healing process/make it go away. Its not bothering me, but visually its not the best thing to have, as I am good about track marks and this is not going to be good in the summer when its hot and long sleeves are not so common.
