Hi,
Greetings!
Welcome to Health care Magic.
Regarding your 1st question that what could be the cause, the diagnosis is Flu or
common cold due to viral infection. Due to continuous cold, there could have been excoriation of skin leading to
Furunculosis, which you are feeling to be a pimple inside the nostril.
Here are the suggestions for you to have quick relief:
1. Steam inhalation 3 to 5 times a day
2. Anti
histamine drugs like
cetrizine shall reduce the running nose and provide you relief
3. Topical ointment
Mupirocin to be applied over the area inside the nose, where you feel there is a pimple like spot. This shall relieve the pain apart from reducing the swelling.
4. Do warm saline water gargling 3 to 4 times a day. This shall soothen your nasal and naso pharyngeal mucosa and reduce the congestion and inflammation.
The 4 steps mentioned above shall give you very much required relief immediately.
Wish you good health. Do let me know in case if symptoms persist. Would be glad to help you.
Take care.
Best regards,
