Have you ensured that your partner doesnt have any STD's? This problem is chronic since past 1 month? Is there any itching?
with best regards,
It can not be perioral dermatitis if it developed after Oral sex for sure. Under any case continuing Betnovate would be ideal for the time being. I also advice that you start taking Neem capsules [see www.himalayausa.com] which is a blood purifier and also take Vitamin C tablets. Slowly start replacing Betnovate with a application of coconut oil mixed with Turmeric. It may leave a stain but will go off on washing. Use neem soaps. this is the best line of treatment for a chronic condition like this.
She had thrush of mouth / vagina? You know its a Yeast infection and if it were to have been in her Vaginal region then that must be the thing which has spread ... most probably. I dont think its perioral dermatitis which would have come down upon intake of the Oxytetracycline. If you dont feel like going back to the steroidal cream thats fine but follow what i advised you instead.
Extremely sorry as i could not come back to you early.
Unfortunately my collegue could not complete as the customer did not come back. As it was vaginal thrush and and not a oral one it eliminates one suspicion. I am doubtful now whether the oral sex could be the culprit. I suspect Eczema. I would honestly advice you to see a dermatologist who can run a smear test on the flakes from the rashes. Flakyness on one side indicate fungal infection. But still to get convinced its better to get a test done. the advices given by me are good for all types of infections. You can anyway start them.
