Hi Roxie,
You are more than likely experiencing a Herxheimer reaction (a
<font color="black">released by the death of harmful organisms within the body). It makes you feel like you have the flu, aching muscles and joints, intensified symptoms, etc...
Biaxin is an antibiotic used to treat Lyme. If your acute sinusitis is viral, the antiobiotic will not do anything to solve this problem, the Biaxin will attack the Lyme bacteria though, causing you to herx.
This is how my dr got the ultimate confirmation that I have Lyme: I was taking azythromycine for a respiratory track infection, and after 1 day I felt soooo bad, never felt so bad in my whole life... The antibiotic was causing a herx... My dr was so happy when I told him how I felt, he was right in thinking I had Lyme.
Please keep in mind that this acute sinusitis might be viral, which means that it'll just need time to clear up. Don't let your dr prescribe you steroids though. Steroids are an absolute no when you're having Lyme and/or coinfections, it only suppresses your immune system more.
Lyme treatment is different for everyone, there is no way someone on here can tell you how long it will take for you to get better. I'm sorry...
