Difficulty breathing and low oxygen levels can be caused by a variety of factors, including:

- Pneumonia: An infection of the lungs that causes inflammation and fluid buildup in the air sacs.

- Asthma: A chronic condition that causes inflammation and narrowing of the airways, making it difficult to breathe.

- Chronic Obstructive Pulmonary Disease (COPD): A group of lung diseases that cause airflow limitation and difficulty breathing.

- Heart failure: A condition in which the heart is unable to pump enough blood to meet the body's needs.

- Other medical conditions: Such as anemia, thyroid problems, or certain medications can also cause difficulty breathing and low oxygen levels.

In addition to difficulty breathing and low oxygen levels, you are also experiencing a rash, itching, and swelling over your body. These symptoms may be caused by an allergic reaction to a medication you are taking, an infection, or another underlying medical condition.

It is important to see a doctor right away if you are experiencing any of these symptoms. The doctor will be able to determine the cause of your symptoms and recommend the best course of treatment.
