Hi, I work in a factory as a part of assembly. I have this strange problem I've been noticing lately with my sinuses. At first I was having a lot of dry blood showing up in my sinus mucus. Then it was fresh blood. I thought it was just a case of dry sinus and started sleeping with a vapor to try and clear it up. Now, the blood is gone but I have reoccurring pimples in my nostrils. They are very painful. What is the cause of this and is it possible to cure? Oh, the pimples have only been appearing for less than 2 weeks.
