I think I may have a Cyst!?! But, here it is: I have a bump on the back of my neck that recently just began to swell a little. Normally, it just feels like a lump. Not to bad. It contains dark grey, white, and pink (from blood & clear fluid; maybe plasma?)
Hi, This is most likely a sebaceous cyst. This is not serious and is easily treated. If it causes you no discomfort then it may be OK to leave alone. If you are experiencing pain then you may consider having it removed. I suggest you see your doctor to discuss the options. Chat Doctor.
