Hello Thanks for sharing your symptoms. Based on your history—seasonal allergies, one-sided nasal blockage, mild shortness of breath (especially at night/warm places), occasional palpitations, and brief episodes of weakness/dizziness/blurred vision—it’s most likely a combination of allergic rhinitis (possibly with a nasal polyp) and mild postural hypotension or anxiety.
Here’s how these fit together: - Allergic Rhinitis/Nasal Polyp: Chronic allergies can cause persistent nasal blockage, sometimes leading to polyp formation. Blocked nose can make breathing feel harder, especially at night or in warm rooms. - Mild Shortness of Breath & Palpitations: These are common with nasal blockage, allergies, and sometimes anxiety. Warm environments can worsen symptoms by dilating blood vessels and lowering blood pressure. - Brief Weakness/Dizziness/Blurry Vision: This often happens with mild drops in blood pressure (postural hypotension), dehydration, or anxiety. It’s reassuring you’ve never fainted and don’t have chest pain or severe breathlessness.
### What’s Most Likely? - Allergies and nasal blockage are the main cause, possibly with a polyp. - Anxiety and mild low blood pressure may contribute to palpitations and brief dizziness.
### What You Can Do - Try saline nasal rinses and antihistamines for allergies. - Stay hydrated and avoid standing up too quickly. - If symptoms worsen, or you notice persistent one-sided nasal blockage, consult an ENT specialist for a nasal exam (to rule out polyp or other causes).
Thank you
Hello
Your symptoms could be related to chronic allergies with a blocked nasal passage, enlarged turbinates, sinusitis, or a nasal polyp, especially since one side of the nose is persistently blocked. Allergies can also contribute to mouth breathing, poor sleep, chest tightness, and mild nighttime breathing discomfort. The shortness of breath and palpitations may sometimes be worsened by anxiety, stress, poor sleep, or nasal blockage itself.
The brief dizziness, weakness, blurred vision, and nausea can happen from low blood pressure, dehydration, anxiety, anemia, irregular sleep, or occasionally breathing-related issues. Mild asthma or allergy-related airway sensitivity is also possible, especially with family history of allergies or respiratory problems.
An ENT examination is important to check for nasal polyps, sinus problems, or a deviated septum. You may also need basic tests such as blood pressure check, CBC for anemia, blood sugar, ECG, and possibly allergy or asthma evaluation if symptoms continue. Seek urgent care if you develop severe breathing difficulty, fainting, chest pain, or persistent rapid heartbeat.
Take care
Your symptoms of long-standing nasal blockage, seasonal allergies, occasional shortness of breath, nighttime palpitations, brief dizziness with blurry vision, and mild nausea may be related to chronic allergic rhinitis with possible nasal polyps or sinus-related airway obstruction, which can sometimes affect breathing quality and sleep. Stress, anxiety, dehydration, low blood pressure, poor sleep, or mild anemia may also contribute to palpitations and brief dizzy episodes, especially at your age. Since the symptoms have been present for 1–2 years and there is a strong family history of allergies or respiratory issues, it would be advisable to consult an ENT specialist and possibly a physician for further evaluation, which may include a nasal examination, allergy management, blood pressure assessment, and basic blood tests. Seek urgent medical attention if you develop severe shortness of breath, chest pain, fainting, persistent rapid heartbeat, or worsening symptoms.
Hello, thank you for sharing your concern. Your symptoms could be related to more than one issue happening together, and fortunately many of the possibilities are common and treatable.
The chronic one-sided nasal blockage with allergies strongly suggests: - allergic rhinitis, - enlarged turbinates, - deviated nasal septum, - chronic sinus inflammation, - or possibly a nasal polyp.
A constantly blocked nose can sometimes contribute to: - mouth breathing, - poor sleep quality, - chest tightness sensation, - nighttime discomfort, - fatigue, - and anxiety-like symptoms.
The mild shortness of breath and nighttime palpitations can occur with: - allergies/asthma tendency, - anxiety or stress, - poor sleep, - nasal obstruction, - deconditioning, - or occasionally mild blood pressure fluctuations.
The brief episodes of: - dizziness, - weakness, - blurry/white vision for a few seconds,
especially when standing suddenly or during stress/warm environments, can happen with: - low blood pressure, - dehydration, - anxiety/panic response, - low blood sugar, - poor sleep, - anemia, - or autonomic/vasovagal responses.
The reassuring points are: - no fainting, - no chest pain, - no severe breathing difficulty, - and symptoms have been gradual/chronic rather than suddenly worsening.
What would be reasonable: - ENT evaluation for the chronic nasal blockage - Possible nasal examination/endoscopy to check for: - deviated septum, - polyps, - allergy swelling, - chronic sinus issues
You may also benefit from: - CBC/hemoglobin, - blood pressure check, - oxygen saturation, - and possibly allergy/asthma evaluation if chest symptoms continue.
Things that may help meanwhile: - Saline nasal rinses - Avoid dust/smoke/allergy triggers - Good hydration - Regular sleep - Avoid excessive caffeine - Slow position changes if dizziness occurs
An antihistamine or steroid nasal spray is commonly used for allergic nasal blockage, but it is better to use them after proper examination and guidance.
Seek urgent medical care if: - severe shortness of breath develops, - chest pain occurs, - fainting happens, - one-sided weakness develops, - severe persistent palpitations occur, - or vision loss lasts longer than a few seconds.
Final Advice: 1. Chronic nasal blockage is likely allergy/sinus-related or structural 2. ENT evaluation is appropriate, especially for possible nasal polyp/deviated septum 3. Dizziness and brief blurry vision may relate to blood pressure, stress, dehydration, or poor breathing/sleep 4. Mild anxiety/stress can worsen palpitations and breathing awareness 5. Basic blood tests and BP evaluation may also be useful
Advice: Your symptoms do not immediately sound dangerous, but the long-standing one-sided nasal blockage deserves proper ENT assessment because treating the nasal issue may improve several of your other symptoms as well.
