Hello lybrate-user, kindly have some patience with the treatment. As you mentioned you have taken allopathic medicines 6 months ago, their side effect also has to be removed. If you want permanent resolution of your condition, just trust your doctor and take all precautions and medicines as advised. Although, you can apply some almond
oil or mustard oil
in your nose but only after discussing with your doctor. You will be relieved soon.
