Please help docs! is my mucous buildup in my throat due to allergies?

It depends...: If you do suffer from allergies it can cause mucus buildup. Unhealthy diets can cause acid reflux that also increase mucus buildup in throat. Seeing a doctor could help differentiate between both to decide which medication would help you best. Lifestyle changes are also beneficial depending on cause.

Allergies: We don't know anything about you, not even any medical history, medications or symptoms suggestive of allergies. Please see your doctor or provide more information when you pose your question.
