Had my appointment with the allergy doc this morning. Thinking ahead, I skipped my morning dose of antihistamines. Good thinking, as the scratch test is now scheduled for 11:00 Monday morning. It's going to be a long and undoubtedly uncomfortable weekend. The doc took pity on me and gave me a sample package of Singulair since taking it won't compromise the test. I can also use Nasonex, but unfortunately I don't have any here with me at work. I wish I did -- I've already got one heck of a sinus headache. I'm not sure which is more bothersome, the headache or how itchy the inside of my nose feels.
