I have been having severe, dull, aching body pain all over my body. It's accompanied with upset stomach, diarrhea, and fever, though the aching is what keeps me down. I don't think this is just a flu bug. This happens to me very randomly, and started when I was 7. It's been increasing in frequency. I can barely move, my joints hurt so bad. Am I overreacting or could there be something else going on? Thanks.
