@hayley3 -thank you for the recommendation of Vitamin D. Vit D3 is critical for immune support and overall health. Vit D3 improves immune health while decreasing inflammation. Many people are deficient and are unaware how important this vitamin is. It is refreshing to hear advice on starting from within of what you can control, rather than only getting/giving advice to make a doctor appt. What presents as sinus pressure has so many other contributors rather than the sinus themselves. Work with ways, like you mentioned through Vitamins/Minerals to restore yourself from the inside. It doesn’t happen overnight, but it will happen and consistency is key. There is no rx that can take the place of vitamins and minerals.
Thank you for the real advice.
