I always dread taking antibiotics, since they do a number on my stomach. This time, while taking Cleocin, I was sure to eat lots of yogurt and started "Threelac" probiotic. But........about half-way through the antibiotic course, my esophogus would hurt immediately after taking the pill. It felt like food couldn't get through very easily. The bottle warned to always take it with a glassfull of water, which I did. The last antibiotic was several days ago, and my esophogus still spasms easily. Does anyone else find that happening with antibiotics? Thanks.
