Hello I was diagnosed with eosinophilic esophagitis and some inflammation in my stomach (was never told the name, possibly gastritis, eosinophilic gastroenteritis??). I treated with glucocorticoids and ppis for 6 months. This was 3 years ago. I called doctor who diagnosed me, but he won't call back, I got to the receptionist and she left a message. Can these conditions be responsible for the elevated RF? Does anyone know??? I have symptoms of fatigue, gas/bloating, brain fog, feeling very slow and sluggish, I cannot do hands-on things fast enough because my brain is just slow and sluggish. I had a colonoscopy with biopsy and all was normal including biopsy. Any advice? So far my plan is to call and ask to speak to another GI doctor and speak with him instead.
