Persistent fungal infection in armpit

Hi - I have had what has been diagnosed as a fungal infection under one armpit for nearly 18 months.  Originally I had it in 3 places and 2 went quickly.  That under my armpit has responded to treatment (Canestan HC) and then come back several times.  I was asked to use Daktarin last December and again it worked.  But now it is back with a vengeance - bigger than ever.  I am using Daktarin again and it appears to be less angry looking but is not exactly retreating.  I wonder if anyone has any advice which might help?  Could it be a bacterial infection instead and, if so, what is the approach?  Many thanks in advance for any help.

Who gave you the fungal infection diagnosis and based on what?

Thanks for your interest Indio.  My GP did the diagnosis on both occasions.

 

Basex on biopsy or another test?

Based on inspection by 2 different doctors.  No tests but seeing another GP on Friday for a review.  Are there tests I should be seeking then?  Thanks for your interest again.

Some test needs to be done.Ask the dermatologist about that.
