welcome to HealthcareMagic
Your diagnosis may or may not be right and even if it is right i suppose you will not be able to find a solution.I would suggest you that instead of analysing the abscess
(whether a simple abscess or actinomycosis
)yourself please consult a doctor or better a surgeon who will examine you;diagnose your problem and immediately advise you the treatment required whether in form of antibiotic or even an incision and drainage
of abscess if needed.So please consult a doctor and you should be fine.
