Injection lump?

[Fireflygem]

Ok prob an odd question but this is month 4 of 6 prostrap it seems to be when it's put in my left side which I've had a cyst removed from before it becomes a large lump and the flare up lasts longer as getting up or catching it also hurts my preggy looking belly I've had it done Christmas eve and still look like I'm stashing a turkey up there last time it took about a fortnight to go down as well as the hard lump, I've rubbed it, drugged up on the pain killers but any pointers or advice would be greatly appreciated as family keep accidently bumping my lump and I'm due to do a uni placement in a school starting Jan so fingers crossed it's gone by then thanks in advance also anyone had any sideaffects with citalopram and prostap 😅
