Well I guess anything is possible, but I have never heard that reflux was due to anxiety. Have you had a endoscopy done? I'm wondering if you have a hiatal hernia and that is the lump in your throat you are feeling? I really think you should get back with your doc and if you still aren't doing any better.
I think this calls for more testing to be done. What med(s) are you on for the reflux?
I have hypothyroidism (1953), diabetes type 2 (1976), high cholesterol (1989), gastroparesis (1990), FMS (1995), and GERD (2006). I am on these meds for FMS: Prozac 20 mg., Xanax .5 mg., Diclofenac 100 mg., Cytotec 200 mcg. (stomach med to go with Diclofenac), Lortab 10/500 mg. I am also on the other meds for various reasons: Nexium 40 mg., Cytomel 50 mcg., Detrol 2 mg., Reglan 10 mg., Novolog insulin, Novolin N insulin, Bumex 1 mg., Lipitor 80 mg. & WelChol 625 mg. 3 a day with dinner. Also on B12 sublingually, magnesium, Centrum Silver Vitamin, CoQ10.
