sinusitis
"My sinus infection was hard to diagnose. Thought allergy meds were causing post nasal drip. Then my lungs were inflaming to the point I couldn't play racketball. Got to my allergist, it took a week. By then I was contemplating getting on oxygen by going to the hospital, but prescription finally came for Doxcyclin. Though 22 days of 30 It eased things up. Started the Biaxin just a few days after the end of the Doxcyclin. Dr warned me of aluminum taste Pharmacist warned me of needing food. Never noticed any stomach upset. Stopped taking with food, but always with a big glass of water. Only noticed metalic taste a few times waking up with foam in the back of my throat, but by the 3rd day that was gone. I'm on the 2nd week and starting sprints."
