On rainy or cloudy days, my right side feels dizzy and my nose feels bad.

The head is the place where the Yangs meet, and the Qi of the clear Yang of the six fu organs meets here. You have nasal congestion caused by rising turbid qi, causing dizziness and headaches. There is an imbalance in the rise and fall of clear and turbid qi. The turbid qi is stagnant in the clear orifices, and the clear yang is not flowing, leading to headaches. Generally speaking, exogenous symptoms are mostly symptomatic, and the treatment is mainly to dispel wind and eliminate evil. This is what Western medicine calls dizziness and headache caused by sinusitis.
