Hello and welcome to hcm.
I have read your question and I can understand your concerns.
What is her age..?
Does she run fever.?
Is she diabetic or immunocompromised.?
If i were her treating physician HERPES infection would have been on my top list.in this condition vesicles appear in dermatomal area of skin ie along the nerves.i would have tzanck test to confirm it.treatment is done with
antiviral such as
acyclovir 400mg.
2nd on my list would have been boil which is the infection of hair follicles and causes lumps with pain and pus inside.i would have prescribed antibiotics such as combination of
ampicillin and flucloxicillin 500mg 4 times a day.
I would have looked for pilonidal
abscess which is usually present in the cleft of buttocks.usually it is given a trial of antibiotics but definitive treatment is surgical excision ie karydakis procedure.
I would have looked for any abscesses .
I would suggest you to meet a
general surgeon or a medical specialist.
Thanks.
Hope the answer is helpful.
Feel free to ask further questions.
