Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain small painless bumps on
scalp that comes and goes can be due to causes like
Contact dermatitis leading to some sort of
allergic reaction..
Other causes of bumps on scalp can be
folliculitis, sebaceous cysts,acne,hives etc..
The exact cause can be ruled out only after a thorough clinical evaluation and investigations like microscopic examination of scrapings from the bumps,
biopsy, blood tests etc..
I would suggest you to consult a Trichologist and get evaluated and he can decide treatment depending upon cause..
As they are painless no supportive treatment is needed as of now and should take only treatment as per cause..
You can however take anti allergics like Levocetrizine to resolve the bumps soon..
Maintain cleanliness of scalp..
Avoid scratching the bumps to prevent infection..
Hope this information helps..
Thanks and regards.
