sinusitis
"I have had chronic sinusitus for 30 years. Sometimes 4 per year and we had to do cultures to make sure we got the right bug after have numerous antibiotics failed. I think allergies and maybe viral infections start it off and then it turns into an infection. This medication has worked for me over the last 10 years ,although we have used other drugs to good effect. I have had few side effects except for dizzyiness and some brain fog for a few hours after taking the drug. It works very quickly on my infections but I do worry about side effects. I have been an avid weight lifter  and never slowed down while on this med and had no issues with tendons or aches. This time I will take it a little easier and just keep my joints and muscles moving!"
