About a month ago I had a stomach bug with diarrhea & vomiting. Had a temprerature 38,4 C. After a few days it was ok. As I was nervous about my health, I went to gynaecologist, who said everything was ok & to the gastroenterologist, who examined me and also said I was ok, but she diagnosed me with IBS (earlier I had some more frequent bowel movements). Since about 3 weeks I ve been having a low-grade fever (37,2 to 37,6 C). I went to see a GP and had my blood (with CRP and ESR) and urine work done. All the results were ok. I have no other symptoms: no pains, no fatigue, etc. Sometimes at night I feel a bit hot and during the day a bit cold (I m usually cold during autumn and winter) My doctor said she has no idea why my temperature is raised but said I shouldn t be worried. I ve been suffering from health anxiety for over a month now. Also, sometimes I can feel a pulsating feeling in my stomach and some heart palpitations. I sometimes wake up during nights. I m a female, 28 years old.
