concernedabout

Ok, So I have this bump/Scab/Blister thing on the back of my head right where my head connects with my spine, on the left side of my spine. This started about three months ago. I originally thought that i had accidentally scratched my self nand broke the skin causing a scab to form. One day it began to bleed from me picking the scab. The only wierd thing that i noticed was that it would bleed much longer than any other scratch before scabbing up. So for the past 3 months i have been treating this thing with Neosporin and it is still there. It will bleed, then scab, then turn into a blister like fluid filled bump before bleeding again. Sometimes it will just start bleeding out of nowhere. I can also feel dull pain pressure in my neck around this bump. I believe that it is the cause of my neckaches that i have been having. What could this be. The only oher bump that I have had like this was on my ear. This was about 5 months ago. It looked just like this one, but never bled (probably because i didn't pick at it as much). I thought the one on my ear was caused by talking on my cell phone too much because the phone reciever would get really hot after talking for a while.
