I have been shaving my vagina area and I noticed a lot of chaving and soreness in the area as i shave all my hair and very close to my vagina opening.

However today i noticed on the right side of my vagina right near the opening there was a significant sting and sore patch, i look for bumps but there is barely anything there besides some redness although the patch feels a bit tough and only ever so slightly swollen (like two little small swollen bumps or maybe one) when i touch the small short spikey hairs ive missed shaving there, they cause pain like it's in the area and underneath the skin. it feels a bit worse throughout today and into a bit more of a bump although nothing to squeeze as no 'head' or bump is there. it stings when im not touching it but it could be the sharp razor burn, i dont know! i have had alot of ingrowns this time around shaving just never on this patch of hair so so close to my vagina thats why im scared.

there is no itching, just the a strong pain/sting/burning feeling (burning feeling could be when i put a cream for pimples on the area because i usually do that with my ingrowns and they go away but this hurts like helllll) i whiped it off because it hurt but stings like hell.
The area is redder than the other side but no visible bumps present just slight bump when touched

I haven't had unprotected sex or sexual intercourse but had sexual contact about 4 days ago very briefly. I am stressed and scared it's something bad as it really hurts. I have no other symptoms but the areas below it (shaved also) is a bit sore too

i am just completely paranoid it's something bad because its so so painful, it has gotten worse but i have been touching it a bit because i have been trying to work out what's wrong.
Does it sound like something bad? it has only come up today and is only painful today but the pain has allevated as the bump has
