Hi can any body help me to figure out this..

I have a hard bump on my right labia majora in the hairy part and pains a lot..the whole labia majora is itchy ...few days before the whole vagina part was itchy, now it got better...

I am sure its not a STD.

Is it because of consuming any antibiotic??? bec i took some tablets for cold (chestrol cold)..

and I am in a remote area, cant consult doc immediately...
