I was diagnosed with PF about 1 1/2 years ago. I think it was caused by all the smoke from wildfires in the region where we live. I was fortunate to find a very good doctor in Portland, Oregon, who has reviewed three breathing tests and two CT scans over this time. He has taken a calm approach to my illness unlike the first doctor I had who wanted me immediately to take Ofev and go on oxygen at night. Yes, I cough a lot and have some problems breathing when I try to do too much but I have still kept playing golf and taking one-mile walks with my wife and dog a few times each week. I even joined a gym although I only use it to ride the stationary bike. The $35 per month fee is covered by my Medicare Advantage plan. Looking forward to something really helps my mental health. My wife and I set aside every Wednesday to drive to the Oregon coast for lunch and a walk along the ocean. We are also looking forward to some time this year to do visit some state parks with our very small RV. Visiting some family members is also on the calendar this year. I hope this helps you find some ways to get your husband off the couch.
