Hi Klee,

Thrush can cause really uncomfortable feelings down there. Best to get it checked. Common in pregnancy and it can cause swelling which may be the feeling you describe. The sensation can come and go! You don't necessarily have to get the discharge with thrush.

As to certain foods causing symptoms, allergies to certain foods can cause leukorrhea (whitish discharge). I have a reference on this but I can't find it just now. Wheat is a common one.

Then again, thrush can be affected by what you eat as it especially likes to feed on sugar.

Let us know how you go and I hope it clears up soon.
GIDGET.
