What Causes Painful Lump On Left Clitoris And Fatigue After Having Sex?

i have a small hard lump which is the same colour as my labia on the left side of my clitoris and the skin in betweenthe clitoris and the lump is peeling off. The area around my clitoris is dry,red in colour and it is really painful when i touch there. My clitoral hood is swollen and a little hard than usual.I had sex with my boyfriend 5 times and we used condoms.The last time i had sex was 3 weeks ago. I had my periods one week before the day i was suppose to have it but it lasted only for two days and i also had a light fever,nausea,fatigue and a headache during these two days.I have a loss in appetite and everything i eat tastes bitter. I also have some small red spots on my tongue. I haven't checked for any STDs and i didn't take any medicine except for paracetamol.I would really appreciate it if someone could give me a solution. Thankyou :)
