Normal symptoms for hiatal hernia ? Burning pain/nausea + st

I have been having alot of burning pain/nausea for years. It radiates above my stomach & between my ribs. Within the last year i have been experiencing severe pain & pressure in my stomach that comes & goes. I havent had an appetite for a couple days so i haven't ate much. Yesterday i had the worst pain yet. My stomach started cramping really bad with sharp pains. Hurt so bad i could barely walk. When i laid down i had so much pressure pushing up that i had shortness of breath (which scared me!). I took a nexium & a zantac & about 2 hours later the pressure was relieved but still had excruciating pain in my stomach & between my ribs. Then all of a sudden i got the chills really bad & started shaking all over & had a fever (normal temp is around 96.4 for me) I took Tylenol & fever came down within the next hour. Today i woke up with really bad nausea & the same awful gripping stomach pain. Is this normal with a hiatal hernia or is this something worse? Thanks for reading!
