After visiting a dying mother at two nursing homes I have come down with something I can't kick. At this time I have been using Levaquin and now Amoxicillin. (5 weeks) Have used Duo-Neb with Nebulizer machine and Azmacort daily for the past 5 years. I was diagnosed with Asthma as a child. Now 71 years old. Lately my PFM has been 270 average. Oxygen concentrator for 12 to 15 hours a day. Was rear ended in 1980 in a auto accident . Sustained Neck and Low Back major chronic problems. 28 years fighting and arguing with MD's over Chronic Pain. I'm just a DRUG ADDICT !! The coughing to get up sputum is now a major source of increased pain. Could use some good advice. veejer
