swelling in throat

July 10th of this year after eating pizza i felt a slight lump in my throat. this sensation lasted for a while and then had some feeling of swelling in my throat. no other symptoms . no coughing, no bleeding, no fevers...NOTHING! this lasted 4 weeks (onand off) until i went to the ENT and he did a rhinoscopeno fun at all) and said my throat was swollen and said its reflux. he put me on Omeprozole (sp) 40mg 1 time a day. it seemed to work a little bit. i avoid all the trigger foods...ie, coffee, chocolate, onions, friend foods...i dont eat 3 hrs before bed and i sleep propped up. I had a pumpkin latte (like a moron) and OH MY GOD my throat swelled up like crazy.....i went back to the ENT who upon doing another rhicoscope said my nose was imflammed and that i had an infectionin my throat. he gave me 7 days of Avelox and said to keep taking the Omeprozole. I went for blood work today because he wants to rule out gsastro bleeding. i have an appt w a gastro guy tomorrow.The ENT is sending me for a CT of the neck as well...I had an ultrasound back in June and there was nothing wrong. I had blood workup in June and all counts were fine. NO Thyroid issues at all. I am 36yr F in pretty good shape....(maybe need to lose 30 lbs) but overall i eat healthy and exercise everyday... ugh!
Is this reflux???? orcould it be a spasm in the esophagus.  I have no heartburn at all. sometimes i taste a funny taste in my mouth but other than that nothing.
