Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.

 

In the Name of Allah, Most Gracious, Most Merciful.

 

All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.

 

As long as you have cleansed your nostrils by using water as best as you can, you need not worry: your wuhu is valid.

 

We may do well to remember that Allah does not place on us burdens we cannot bear.

Allah Almighty knows best.
