Experiencing sudden shortness of breath can be alarming and may stem from various causes. Based on your description, it seems you are encountering episodes of feeling like you cannot get enough air, which requires you to take deep breaths to alleviate the sensation. Additionally, you mentioned having some phlegm in your throat, mild nasal congestion, and occasional dry cough.
Firstly, it's important to recognize that shortness of breath, or dyspnea, can be caused by a range of conditions, some of which may be respiratory, while others could be related to anxiety or other systemic issues. Given that you do not experience chest tightness, this may suggest that your symptoms are not primarily cardiac in nature, but rather related to your respiratory system or possibly an anxiety response.

One potential cause of your symptoms could be related to your nasal congestion. When the nasal passages are blocked, it can lead to difficulty breathing through the nose, which may cause you to breathe more through your mouth. This change in breathing pattern can sometimes lead to a feeling of breathlessness. The presence of phlegm in your throat could indicate post-nasal drip, where mucus from the nasal passages drips down the back of the throat, leading to irritation and a sensation of needing to clear your throat.

Another possibility is that your symptoms may be linked to an underlying respiratory condition such as asthma or bronchitis. Asthma can cause episodes of wheezing, coughing, and shortness of breath, particularly if there is an allergic component or if you are exposed to irritants. Given your history of nasal allergies, it is plausible that you may be experiencing an asthma exacerbation, even if you do not have a history of frequent asthma attacks.

Anxiety can also play a significant role in the perception of breathlessness. Many individuals experience shortness of breath during periods of heightened stress or anxiety, which can create a cycle of fear and hyperventilation. This can lead to a feeling of not being able to catch your breath, even in the absence of any physical respiratory obstruction.

To address your symptoms effectively, it would be advisable to consult with a healthcare professional who can perform a thorough evaluation. This may include a physical examination, lung function tests, and possibly imaging studies to rule out any underlying conditions. If asthma or another respiratory condition is suspected, a trial of bronchodilator therapy may be beneficial.
In the meantime, you can try some self-care measures to help alleviate your symptoms. Staying hydrated can help thin mucus secretions, making it easier to clear your throat. Using a saline nasal spray may also help relieve nasal congestion. Additionally, practicing relaxation techniques such as deep breathing exercises or mindfulness can help manage anxiety and improve your overall sense of well-being.

In summary, while your symptoms may be related to nasal congestion and potential respiratory issues, it is crucial to seek medical advice for a comprehensive assessment. Understanding the underlying cause of your shortness of breath will be key in determining the appropriate treatment and management strategies.
