Well ?

So I shaved my vagina maybe a week ago or a little over 2 weeks ago and whenever I shave I get itchy and sometimes I get a bump. Like if I shave under my arms it’ll be sore and I’ll grow a bump. But this time my vagina has a bump on it. Can it be from irritation from shaving or should I be concerned. It’s not burning or itching. It’s just a little bump that’s sore. FYI I haven’t had sex in months.
