Hello. Thank you for writing to us
I suggest a possibility of deeply situated bacterial infection of skin and
soft tissue (SSTI's) i.e either a Furuncle Or a Carbuncle with surrounding
cellulitis.
Sqeezing has probably pushed it deeper.
The fact that it still feels hard, swollen and painful even after emptying its contents suggests that there is still infection remaining inside.
I advice you against squeezing it as this may push the infection further deeper and into the surrounding soft tissue.
If I was the treating doctor I would have suggested you a course of an Oral antibiotic for a week.
My choice of an oral antibiotic would be either flucloxacillin or
cephalexin for a week.
Oral antibiotics are prescription drugs and therefore I suggest that you talk to your doctor for the needful.
Topically you may use an OTC topical antibacterial e.g 2%
mupirocin ointment, twice daily for a week.
An OTC oral anti-inflammatory e,g Ibuprofen twice or thrice daily will provide you symptomatic relief from pain and bring down swelling.
