Throat Lump, Nasuea & Panic

Just before 3 weeks I had terrible sharp pain below chest  which was later followed by nausea and then feeling of lump in the throat  (swallowing trouble) and then panic jerks while sleeping. Suddenly my eyes are also staying dry and cannot read properly. My mornings use to start worse and at  nights I ended up better. Dr. prescribed me with Nexium 40mg per day along with some tests (glucose/LDL/Trigycerid were little abnormal). Before 3 days I did slow jogging for a mile and shockingly ever since then my throat problem has escalated along with severe nausea which now stays even at nights. I feel weak and sleepy but when I try to sleep it gives terrible panic jerks and wakes me up. On my 2nd visit Dr. visually checked my throat viewing inside the mouth and inspected by pressing the throat from outside and increased Nexium to twice a day and prescribed thyroid test whose results yet to come.

(I had the same situation before 10 years, I had done biopsy/barium/endoscopy all came to be negative with just minor stomach inflamation (inflammation). I was depressed and  lost about 30 pounds. For 1 year they treated me with antacids, depression pills, consulation  for panic attacks with not much help until I moved to a different city and surprisingly all the symptoms disappeared completely.)

Not sure if I have gerd or something else (sometimes I do feel stomach burning now), I feel terrible, depressed and cannot affort to stay like this too long again. I need to know if anyone has gone through this situation before and is there any cure or answer for this ?
