About a month ago I had this werid mark on my arm that kinda looked like a needle mark but without the puncture wound, but I ignored it cause it didn t hurt and it wasn t swollen and didn t bleed or anything, now today my friend pointed out the same looking mark again and I looked and there s another one, except now it s a little bigger and it looks like there s 2, it looks like a tiny round bruise in the crease of my arm around where you d put in an IV, idk if I should worry about it since there s no pain or anything, it s kinda just there
