Do cyst make you faint?

I've had a swollen painful bartholin cyst since the 22nd or 23rd...

It hurts to lay down,walk or sit in many positions...

I have an appointment at planned Parenthood on Tuesday...

(It goes down some nights with Advil but enlarges again once I have to move in the morning)

But now I'm worried I should go in sooner because I randomly fainted yesterday around 1:45pm

I can eat and sleep fine

We had just finished eating like an hour prior...

We were walking and suddenly things started fading darker in switches,I call out to my bf right as I passed out and luckily he caught me.... I was out for about 20-30 seconds they said...

Woke up and was fine physically...

My anxiety went wild after though:/
