Hi! thanks for writing to us sharing your son s health problem! After going through your description, I could summarize that the head/temporal lumps are multiple, discrete, small, nodular, solid, painless, ? mobile and itchy! This is a common problem in young children and not to worry about these. I would consider following possibilities in this case as follows: 1. dermoid cysts 2. inclusion sebaceous cysts 3. lymph nodes 4. scalp skin infection 5. benign tumor or tumor-like conditions Therefore, you need to see a physician for a clinical assessment and possibly a needle biopsy for confirmation and to discuss the possible line of treatment! regards!
