Thanks for posting your query at DoctorSpring.com
I can understand your concern.
You seem to be having a very severe furunculosis which is a bacterial infection of the skin.
Tea tree oil won't be effective in resolving the infection. You will need a course of oral antibiotics like azithromycin. Application of mupirocin cream twice a day will further aid in healing. It will be best to avoid shaving of the area till the time the lesions heal.
You will need a prescription from your doctor for the medications.
Please let me know if you have any queries.

Thank you so much for the response. You have put my mind at ease. I will get the medication as soon as possible. Just to confirm though, it is not an STD right?
Thank you for the follow up.
No no it is not an STD. It is a bacterial infection, an infection of the hair follicles.
Please start the medicine soon and update me in a couple of days time.
