I haven't post on here but once, but I read your posts often. I have been struggling with my breathing a lot since last fall. I have moderate copd by my pft. Mild apical emphysema on Ct scan. I have had asthma all my life. Smoked for years, trying to quit again, its a struggle! Last fall on my Ct scan also showed a mass in my thyroid, so large my trachea was deviated. So the beginning of November had to have half of it removed. Thought that was going to help, maybe it has? Started breo after that , which was helping but had to stop it due constant thrush. So back on symbicort. Got a severe cough in January, steroids and antibiotics, pneumonia I guess. Struggling ever since now back on steroids. Sorry for the long post. Just at a loss of what to do next , didn't know if supplements would help or collotal sliver? Any advice would be appreciated.
