Thanks for sharing your recent health problem with us! After going through your description, if I were your family doctor, I would like to consider few possibilities in your case as follows:1. A neurofibroma or dermatofibroma like benign skin tumor2. An inclusion cystsebaceous cyst or a bursa like inflammatory cyst3. A lymph node due to infection in the scalp, ear, neck etc...! Therefore, it is not a thing to worry much but is must be diagnosed properly; therefore please see a local doctor for a physical examination and confirmation...!regards!
