I've been taking Ceftin for just about three weeks now-500mg once a day. For the past two evenings within 1 hour of taking it I have gotten incredible right sided chest pain. I get occasional esosphegeal spasms and it feels like this, but lower down.
Last night it was directly under my right breast. I googled to see if that was a side effect, but not finding much.
I have tried taking Tums and it seems to help a bit.
