Hi, I have a problem in my nose. I have a one-side blocked nose but the side that is blocked can shift. For instance, if I lie down on one side, that side will become blocked. Usually, my right side of the nose is blocked. I also have one-sided nose bleed, which is usually on one-side of my nose. The nose bleed was quite frequent since last month, about once a week. The nose bleed usually accur at night or in the midnight and the nose bleed will just last for a few seconds. I have a pea-sized lump behind my ear and another behind my neck near to the spine.
