I had a jab 24hrs ago 2ml into my right glut and once i pulled out there was some blood and then within around 5-10mins after i had a discomfort in my glut and that night asleep if i rolled over it feel tender if i put weight on it then i noticed it was swolen. Could this be a abbsess? would that show so quickly? Or could it just be mussle damage as i think i may have knocked the barrel while it was still in my mussle. Thanks in advance
