<s>[INST] Had an infection in my naval and the doctor gave me anti-biotics 500mg 4 times a day, that night after taking 4 i was up all night throwing up. I stopped taking anti-biotics and the nausea is gone but i feel very fatigued all day and have no appetite. [/INST] Hello, Welcome to Chat Doctor, If it is a simple infection like a fur uncle, with no surrounding swelling or fever, a local antibiotic cream like Bactrian (mupirocin) is sufficient after cleaning the area well with an antiseptic lotion like Betadine. The symptoms of poor appetite and fatigue would be due to the side effects of the antibiotics. Since you have stopped the antibiotics, it will disappear in a day or two. If you have further queried, I am available. Wish you fast recovery and good health. </s>
