Please I beg you tell me what this is...

I already have an appointment to go see the gyno next week but in the mean time, can someone please help me identify what this may be? Ive only had 1 partner for 6 years and this just began about a month ago. It all went left after taking Keflex (antibiotic) because the next day i got intense itching, burning and the whole thing was so sore and painful. I took Azo yeast, assuming it was a yeast infection (never had one before though) with no relief. Took vaginal probiotics, no relief. Took Monistat, relieved symptoms for a few days. itch returned. Throughout all of this i have been unable to withhold any time of penetration, example: tampons. the monistat took me an hour to get in because of this. Then i noticed when attempting to put anything in , the left wall inside just feels bad. When feeling it right now i feel a lump inside of each cheek...they come and go though because sometimes i wanna feel for them and theyre gone. Lymph nodes? Bartholins? CA? n also, my mother gets frequent yeast infections. so theres some family history. What are we thinking? Please sugar coat because im a hypochondriac and im praying i dont have cancer. could it be a yeast infection getting worse? this all began a month ago right now im asymptomatic aside from occasional itching.
