Ayurveda addresses scaly skin lesions by identifying imbalances in the Vata, Pitta, or Kapha doshas and focuses on internal purification and topical nourishment. Treatments are tailored to whether the lesion stems from conditions like Kitibha (psoriasis), Vicharchika (eczema), or Dadru (ringworm). Ayurvedic texts attribute these conditions to "Viruddha Ahara" (incompatible food combinations), such as consuming milk with fish, as well as the suppression of natural urges like thirst or sleep. These factors lead to the accumulation of Ama (toxins), which then settle in the skin (Tvaka) and blood (Rakta)

Namastey Based on your description, the rash has been present for approximately four weeks and involves multiple areas, including the groin, underarms, chest, and abdomen. Conditions such as tinea corporis (ringworm), eczema, psoriasis, intertrigo, contact dermatitis, and certain other skin disorders can sometimes have overlapping appearances, making it difficult to establish a definitive diagnosis based solely on a description or even photographs. The fact that both the dermatologist and homeopathic practitioner have considered tinea corporis suggests that a fungal infection is a significant possibility, but it is important to understand that skin conditions can occasionally mimic one another. Persistent pigmentation with mild redness can also be seen during the healing phase of some skin conditions. Regarding your concern about diabetes or HIV, it is important to note that a rash alone does not confirm either condition. While recurrent or persistent fungal infections can sometimes be associated with underlying health conditions, the appearance of a rash by itself is not sufficient to conclude that diabetes, HIV, or any other systemic illness is present. Similarly, the fact that your partner has not developed similar symptoms does not necessarily confirm or exclude a fungal infection, as individual susceptibility and exposure can vary.
