nancy thanks for your input......the sores seem to have gone, I am starting the regimen today in hopes I can tolerate it......I've got to try to bring down the Mac. I am so sensitive to medications....no matter what I take it "gets me", so i may as well try to tolerate the Azithromycin. Dr. Swenson isn't overly concerned about the side effects I report. I guess I have to trust him.
