Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain yellow blisters over the scalp along with oozing fluid can be due to causes like Hair
follicle infection or
folliculitis,
Impetigo,
allergic reaction etc..
I would suggest you to consult a Trichologist and get evaluated and a thorough clinical evaluation and investigations like microscopic examination of the scraping from the scalp, blood tests, fluid culture etc can help in diagnosis and treatment can be done accordingly..
You can be advised to apply an antibiotic ointment over the scalp..
You can apply steroid lotion ..
A sort course of
oral antibiotics can also be advised..
Keep the scalp clean and wash every alternate day with a mild shampoo..
Avoid scratching the scalp as it can increase the spread of infection..
You should also avoid moisture accumulation in the scalp as it acts as a medium for growth of microbes that cause infection..
Hope this information helps..
Thanks and regards..
