Hi there. Thanks for writing in to HCM & for a detailed history & clinical features which does make our task of helping you out that much easier! From all that you have stated, No it does not appear to be a fungal infection to me. It appears more to be an allergic phenomenon & most likely a photoallergic reaction & /or more specifically a phyto-photodermatitis & it may be related to the plants in your region. Please trying applying a topical betamethasone-fusidic acid cream locally to the area & taking an antihistamine. This should help relieve your symptoms. Ideally, go across to a dermatologist & do some patch or prick tests depending on what the suspicion is on (allergen i meant) & this may help give you a clearer picture for closure & one can avoid implicated allergens. Trust this was clear advice & gives you a clear action plan. Good Luck! Dr Praveen Rodrigues MD Dermatologist, Cosmetologist, Venereologist Bangalore, India
