Terri, starting Jan. 1 I began to have hard chest pain upon swallowing. Not heartburn, no burning and no acid backing up in my throat , just a hard , slamming pain. The pain would spread to behind either or both breasts, into my back and shoulders, to my neck and jaw and ear. The Dr gave me Aciphex . I did not get better. I had a Barrium Swallow that showed a large ulceration or mass. I then had to have an Endoscopy , that was in Feb. The endoscopy showed nothing wrong ! Now where was the mass that the barrium swallow showed? They don't know , either it was a shadow or had healed already. Well if it healed then why do I still have the pain?? 5 weeks ago the Dr had me take 2 PPI's per day instead of one, I did that for 3 weeks, no change. I then added an H2 Blocker and 3 magnesium tablets per day. I have a FEW better days, not good , but a tiny bit better. Today it is pretty bad again. I feel like I have a knife sticking in the right side of my throat and the pain on swallowing is behind the right breast. My pain moves around. Now they suspect esophageal spasms and say if I am no better next week they will have to schedule the manometry. How I am going to get thru that I do not know. I'm scared as you are. The endoscopy scared me to death too but it was easy , really it was and I am a big chicken. This manometry is not so cool , not from what eveybody says. We just have to do it , somehow, we can't live like this. I believe all mine was brought on by 18 months of Fosamax, I rue the day I took that . Lia
