Around fall 2011 I started having stomach cramps that would come out of nowhere, by november I had nausea, and by december of 2011 I started having loose stools and felt awful. I had a ct scan done in may 2012 that revealed "possible thickening" and my occult blood test was positive. I was referred to a GI doctor who performed a colonoscopy and endoscopy and told me everything was normal and diagnosed me with IBS. By mid 2012 I started having low grade fevers(99.5-100.3) daily whenever I move at all, even just walking around the house. I continued to try and find an answer to why I felt horrible and my primary care doctor had an ultrasound of my neck done since I mentioned several swollen lymph nodes along my jaw area. The lymph nodes were significantly large, so he referred me to a surgeon who said he knew something was going on because of my constant fevers and swollen nodes, but pretty much gave up and said he didn't know what was wrong. I decided to try and move on with my life the best that I could, but every morning I wake up with TONS of gas and bloating, then proceed to have loose stools. I decided to see a GI doctor last month, who ordered many blood tests and an MRI scan. The doctor's nurse said I had a "slightly elevated" crp of 8.4, and my vitamin D level was 18, other than that my blood work was normal. My MRI was also normal, so now my doctor wants me to have a colonoscopy and endoscopy done. I've tried cutting out gluten, dairy, sugar, etc and nothing is helping my symptoms. If not crohn's, what else would cause loose stools, fatigue and fevers?
