<s>[INST] My boyfriend has a hard unmoveable lump at the base of his scull and neck connect, it does seem to change in size at times depending on his stress levels and then while rubbing his neck and shoulders I found another lump in his shoulder mucle near the spine. I dont know what kind of doctor to take him to or what it is. [/INST] Hi! Thanks for writing to us sharing your friends' health problem and giving us an opportunity to discuss once again on the occurrence of hard, fixed lump on the nape of the neck region. I usually consider few possibilities in such cases, as per my experience of fine needle biopsy reports and these are as follows:1. Lymph nodes due to certain chronic or acute infection in the surroundings like scalp, ear, neck etc. 50% cases2. Benign cystic conditions sometimes getting inflamed 30% possibility3. Benign tumor or tumor-like conditions like neurofibroma, lipoma or dermatofibroma etc...20% possibilityTherefore, this is not a thing for mush worries but should be properly investigated; please see a general physician first for confirmation of the diagnosis and then move to specialist according to the diagnosis.
