I'm a bit worried about my husband. He had a viral fever, cough, and weakness. Thankfully, his fever's gone, and his weakness has improved, but he still has this cough. When he coughs, he struggles with shortness of breath, and even when he tries to take deep breaths, it triggers his cough. He's currently on Gudcef 200 and Windose tablets, as prescribed by the doctor. Any advice on how we should handle this situation?
