Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that a recurring raised bump at the back of neck that has a small dot at the top with
redness around it and that was initially itchy can be due to causes like Hair
Follicle Infection or
Folliculitis, ingrown hair,boil, infected gland in the area,sebaceous cyst etc..
I would suggest you to start apply antibiotic ointment over it like
Triple Antibiotic Ointment.
You should do cool compresses over it..
Avoid repeated touching or scratching it as there can be spread of infection with it..
In case if there is no improvement or it keeps recurring
consult Dermatologist or a General Physician and get evaluated and he can do a clinical examination and also do a microscopic examination of the scrapings from the lesion and blood tests to confirm the cause and treat you accordingly..
Hope this information helps..
Thanks and regards.
