urinary tract infection
"Realised I had a UTI after waking up with the symptoms I'm sure you all know...so decided to book an appointment as soon as possible. First dose I had a bad headache and nausea but nothing unbearable and by the second dose my symptoms were starting to disappear less than 24 hours after starting the medication. Nausea is still there about 2 hours after I take a pill but I'm nearing the end of my course. I understand that some people have bad reactions but in my experience this medication was great at relieving symptoms quickly and hopefully my UTI will be no more in a couple days."
