I suffer from chronic obstructive pulmonary disease, and I come across symptoms such as breathing difficulty, high blood pressure, tiredness, high heart rate, and inability to walk as I become tired after that. In addition, I have been suffering from allergic rhinitis since childhood. For the past 20 years, I have been suffering from asthma, and I have been taking tablet Salbutamol and an inhaler Foracort 200 mcg. Then I did not take medicine for a few days. Now I am diagnosed with COPD by my physician. Am I in trouble? Will I survive, and what are the possibilities? Kindly suggest me some preventive measures and medicines.
