Like Gymdandee said, you might want to give up the L-arginine. Hopefully the humidifier will help. Your sinuses may be getting too dry. You might want to think about cutting back on your dose of fish oil but keep taking your baby aspirin since your Dr does want you to take it.
My blood pressure is border line. I was taking baby aspirin 3 times/wk but the doctor said to cut back to once/wk. I don't think I have sinus problems but do live in a semi-dry climate. I got a humidifier to see if that helps. I am thinking that the combo of fish oil and aspirin, etc. is making my blood too thin.
L-arginine is used to make nitric oxide NO (a compound that relaxes the blood vessels). Although some studies suggest that L-arginine may benefit certain health conditions, other research shows that L-arginine may have harmful effects on some individuals.
A large body of data suggests that NO actually promotes tumor progression.
L Citrulline, like arginine, it can convert into nitric oxide NO.
Be careful!!
Aspirin and fish oil can thin your blood, as you probably already know. Are you having any sinus problems? With being on blood thinners and having allergy problems that might cause your nose to bleed. How is your blood pressure, is it within normal range? Were you taking a baby aspirin or a full size one?
