I have no clue what i could be and i hope it ain’t an sti

this problem first started as bumps i discovered on my labia 2 days ago. i don't know if it has got worse due to me itching. What is weird is that they don't actually itch but my whole body is itchy due to my intolarance for my pain medication oxycodone which i have to take 2 hourly to control my pain. since the oxycodone makes me extremely itchy all over it's very likely that the bumps have become irritated from me scratching them unintentionally. Has anyone seen anything like this? I'm worried as i already have major health problems and a weak immune system .

the first image that does not automatically show is how it how it began after bring just bumps

could that be a reaction to your medication? were they there before u started taking the oxy?
