<s>[INST] Developed a fungual infection using dactarin cream on my nose. Skin became very itchy with a burning sensation. My GP prescribed Daktarin again. The rash has spread and blistered evevntually formed into a yellow crusty scale. Returned to GP and he prescribed to different  Penicilin. Took a swab. Result came back negative!! First course of penicilin will be complete in 2 days. Second in 6 days. Meanwhile my GP promised to fax a letter to the dermatologist on my last visit to him 24 hours ago. [/INST] Hi!! According to your history it is not a fungal infection otherwise it must have responded to dacterin cream which is antifungal medicine. I think it can be case of contact dermatitis to some allergen or photosensitive rash.You will have to meet your dermatologist for proper evaluation. </s>
