Allergic Rhinitis

Assalamualaikum.

Been on MC yesterday due to Allergic Rhinitis (correct my spelling if I'm wrong).
Got it when my bedroom ceiling fan was turn on high speed resulting the dust on the fan blade falling down. Due to my high reaction to dust, my allergic kick in immediately resulting in blocked runny nose and swollen eyes. My head hurts so much due to 'resdung', also known as Sinusitis (correct me if I'm wrong again)

The doctor gave me an MC for 1 day and medicine worth RM 51.00 plus other medicine & consultation, the bill came to RM 71.00. I asked the doctor can I pay partially first as I did not have enough money with me. Got to settle the bill today. The doctor gave me NasacortAQ which is a nasal spray that need to be applied on each nostril once everyday. Today is a bit relief as my nose is not blocked & runny but I still speak with a bit of nasal sound.
