<human>: sometimes i get knots on my head and 2-3 days later they go away. Not painful or anything like that. My wife of a year has just recently felt them and is freaking out that i need to get to the doctor. It is something i have lived with my whole life. I do sometimes get migraines, but maybe once every three months. Please help get her off my back with an explanation. Thank you
<bot>: Hello, Your symptoms could be related to local inflammation or inflammatory lymph nodes. Another possible explication would be the demodulation of the skull bones, which is a common and continuous process.  I don't think that anything serious is going on as you have a lot of years living with this phenomenon.  Anyway, I recommend consulting with your doctor when these knots appear for a physical exam. Checking vitamin D plasma levels is necessary too.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
