I've been having nasal congestion on the left side ongoing for a week now. Every morning when I blow my nose there is a very tough and black mucus coming out and then it bleeds but not much. It's also painful when I touch it. I had severe left-sided unilateral episodic headaches the first 2-3 days but not now it's over. Other than that generally I feel a little weak but that's all. Thank you!
