hello, i had a knot on my neck underneath my ear, and then it moved to crease of my ear on the left side. I went to the doctor and he said not to worry about it. Now, I have a rash on my neck and shoulders. I have been sick on the stomach, loss appetite, and sluggish. I have a sinus infection that is draining in my ears. Can you please give me some advice about what is going on?
