Discussions that mention erythromycin

Allergies board

I was wondering if antibiotics help allergies in anyways? i've had a number of symptoms for a few years now and the only time they have completelty gone is when i have taken erythromycin for other reasons. My symptoms are range from stomach problems to blocked nose, Catarhh at the back of the throat constantly and Major fatigue/weakness/tiredness.
I'm trying to pinpoint my illness, so i can try to get better and this is one of the areas that i'm now looking.

Any help at all would be greatly appreciated.

Thanks :) :)
