sinusitis
"On day 4 with no relief. I have had sinusitis now for 4 weeks. I first got prescribed Amoxicillin 800 which seemed to knock out the infection after just a few days on it. No side effects with amoxicillin. 5 days after completing my antibiotics the symptoms quickly came back but worse this time. Now on this antibiotic - severe head aches which linger all day, severe nausea, loss of appetite which has led me to not eat as much and lost 4 pounds in 2 days. Extremely sleepy all through out the day. Almost wish I never tried this antibiotic!"
