bacterial infection
"I was just prescribed this medication a few days ago and I'm glad I read the information package before hand because there are some potentially yucky side effects to this medication. I initially had no problems with this however last night, on my 4th night of the prescription I woke out of a dead sleep with the worst chest pains I have ever had in my life. I legitimately thought I was having a heart attack it was so bad. I woke my boyfriend in a panic, it was terrifying. I have had panic attack before and I always suffer from acid re-flux but my God this was bad. I have never in my life been affected by a medication the way I was by this one. After a while it did subside but this morning I still have a dull ache in my chest/throat area."
