Prickly Heat feeling and strange belching

Doc, I have been going to a gastrologist for quite some time now.  I went there intitially because I was having stomach pain.  We found out that I had an ulcer during an endoscopy. He found a palyp that was non cancerous and removed it.  I am 36 years old and he put me on nexium

.  I know it's not cardiac related I took a stress test and was fine.  So my doctor had me take a ph test and I failed I didn't do well on the test where you swallow water.  3 of 10 gulps were good, 7 bad. He was testing some sort of pressure. As for the ph monitoring, I had a number of examples that weren't good I think he said I had a number of readings that came back poorly but when I slept I was fine. I noticed while checking out the monitor that I had attached to me that one of the numbers constantly dipped really low down into the 1s at time, especially after I would eat.  I would also notice that when I would have this strange belch that I have, it's very deep sounding and very distinctive that the ph number on the monitor would decrease significanlty.

Right now I'm in a situation where I have a ton of prickly heat that is driving me nuts.  I haven't isolated it thoroughly but it seems to happen more in the evening and I think when I walk around it helps a bit.  It's the most frustrating thing I have ever had to deal with.  Right now it seems to be really bad and doesn't seem to be making any headway.  At times I will be sitting on my couch and it just flares up on me...it is normally accompanied by heat/hot flashes and some sweating.  

Do you have any ideas what this could be?  Can you cc a copy of this to ***@****

Thanks,

Will
