<human>: Been working out pretty intense for the past week now I have a solid lump at the base of my neck by the top of my shoulder.  If I pit my head down or side to side it feels like a nerve is being pinched n it shoots pain up my neck to my head.  Is this muscle related or should I worry?  Im 31 130 pounds
<bot>: Hi! 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 cyst/sebaceous 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!
