question

[https://users.livejournal.com/-nascitur/]

so i had my friend inject me, she is a medical assistant at the clinic i work at. she has done it before and its been fine. but this time i have a lump near the injection sight and its hot and sometimes it itches really bad. im just wondering if this is because of poor injecting or if im just having a reaction to my prescription... or if im not storing it properly? ive been trying to find info on storing it but can find nothing... doesnt say on the bottle either. i called my dr. but shes out of town. i dont know if this has anything to do with storing it but you know, lots of questions come up when one is concerned. anyone know anything about this type of trans dermal reaction?
