For the past week i have been experiencing mild headaches, i feel nauseous, diarrhea 3 times a day but little is coming out, i went to mozambique 3 weeks ago, i did go for a blood test and it tested negative for malaria, any suggestions?

Microbiota: Travel to an unfamiliar location may have altered the microbial flora in your intestine. You may take an anti-diarrhea medication like PeptoBismol. Drink enough water so that your urine is mostly colorless, to avoid dehydration. It is likely to resolve on its own. If the symptoms are still there three weeks from the onset, it would be prudent to see a doctor. Wish you good health.
