Thanks for trusting us with your health concern.
The pimple that you have is likely to be due to a blocked and infected gland or a hair follicle. Since you are having a frequency of micturition, a urinary infection s also likely. This can be confirmed after a routine urine examination.
You need to have oral antibiotics
and pain killers like ibuprofen
to control the symptoms.
Do a hot fomentation in the area till then and apply a local antiseptic ointment like neosporin
on the area till you get the antibiotics prescribed from your physician.
Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Dr. Rakhi Tayal.
