Hello chharris3,
Welcome to the forum. Your symptoms are indicating that you need to get yourself thoroughly investigated.
Shortness of breath ( dysnea) that you have been experiencing can be due to various causes like any lung disease ( COPD), asthma, since you have a previous history of having
pneumonia, you need to get radiology done. X-Ray chest to diagnose or rule out ant disease.
Shortness of breath may be experienced when airflow into your lungs ( through the bronchioles ) are insufficient. If this is the cause you need to get
physiotherapy done and increase your lung capacity. Your treatment will also include some vital medications ( antibiotics, anti-oxidants, antihistaminics, and medicines lke deriphylline to do away with
bronchospasm ), you may need to get your blood tests done also to help you get relief from your problems.
For the back pain change your mattress and take some
muscle relaxant. You can spray or apply a painkiller locally for relief, till you see a doctor.
Eat well, take care of your diet and do not neglect your self. Health is wealth, take care.
