Hello,
Swelling inside the nostril can be due to several reasons, such as irritation, an allergic reaction, or an infection. Betamethasone cream is a steroid and may help reduce inflammation, but if thereâs no significant relief, it might indicate an underlying issue like an infection or persistent irritation that requires further evaluation.
Next Steps
I recommend avoiding self-application of creams inside the nostrils without medical supervision, as the skin there is sensitive. Instead, consult your doctor for a detailed assessment. I am happy to assist you further through an online consultation to guide you on the appropriate treatment. Take care, Dr. Sabarirajan
