Hi, thanks for writing to HCM.Severe pain
along with abscess
formation always suggests an underlying infection. A short course of an appropriate Antibiotic and an Antiinflammatory agent will resolve the issue.
An xray of the involved area is necessary to rule out any underlying bony infection.
Avoid contact with water as the infection may likely increase.
I suggest you to consult your physician for proper management.
Hope this information is helpful. Good day
