I am having strong pains in my stomach. Started in the lower center and then went to the left side. Now it seems strong in the center upper area and seems bloated but hard underneath. Had some Diarrhea day before yesterday and nausea, low fever, headache, low back pain. Went to Dr yesterday and she thought maybe appendix, but white blood count was 6.5 so she thought I should monitor it at home. Feeling bad today but not always excruciating, just strange and uncle comfortable almost like labor pains. How can I know if it s my appendix, my friend also said maybe gall bladder, or just a bad stomach flu.
