I'm really worried about my dad. He's been dealing with asthma since 2010, and now it seems like his condition is getting worse. He's using inhalers, rotahalers, and other meds every day, but it doesn't seem to be helping much. Is there any real cure for this? Plus, he's been having skin issues that I think are from the side effects of all the meds. His overall health is not great either. What can we do to help improve his situation?
