Lump in Labia Majora?

Hi guys. Lately I have been getting these hard lumps on my Labia Majora. They're pretty small and I tend to get them in the summer or when I chafe from wearing certain items. I currently got one out of nowhere on my LM right near the opening of my vagina. I wave been trying to look this up and keep getting all these different kind of cysts that don't quite match mine. Mine is in the actual LIP. Not inside like the photos show. What should I do? I've been to the doc before who prescribes Fucidin but I had some leftover and have been using it but it's not working. I have tried to drain it CONSTANTLY but nothing comes out no matter how hard I try 😭 now it's just huge and red and angry with me.. advice?
