[|Human|] I had a wasp sting me on the back of my neck last year and a small lump was left over. I tried to put some pressure on it the other day to see if I could get anything out from it and now it has turned into a large cyst about the size of a nickel when it s original size was about half the size of a grain of rice.
[|AI|]  Hi, If I were your treating Doctor for this case of a nape of neck lump, I would come up with only one and one possibility that is a sebaceous cyst or an epidermal inclusion cyst! Nothing to worry about this and try not to get infected there! I suggest you to go for an FNAC test of the lump for confirmation and to relieve your concerns! Generally surgery is required for cure. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
