Hello. I have had persistent nausea for a little over 2 weeks. No pain. Mild tenderness (only with palpation) of epigastric region, which comes and goes. ESR - 52; CRP = 2.6. All other labs normal, including liver enzymes and pancreatic enzymes. CAT scan scheduled for tomorrow. I have a history of GERD, although it has not been noticably active recently. Prescribed Omeprazole 40mg Friday---nausea better, although still have acute episodes. 56 years old, 5 6 , 260 lbs, female. No history of diabetes. Galllbadder removed about 9 years ago. Only other significant history was Melanoma-in-situ with wide-excision 6 years ago---no problems since. Can gastritis---or GERD--cause increase SED and CRP rates? Thank you.
