I took antibiotics and got better but now I'm sick again with the same thing. Should I still take the same antibiotics?

See your doctor. The answer to your question depends on several factors. If you didn't finish your meds the first time you may now have a resistant organism. If so, restarting the same antibiotic may not work. Also, although your symptoms may feel exactly the same, similar symptoms may be caused by many different things. You should be examined again to determine proper treatment for your current illness.
