Hello,
Apart from allergies and contact dermatitis, other possibilities are of eczema and psoriasis
skin. Psoriasis is a long-term (chronic)
skin problem that causes
skin cells to grow too quickly, resulting in thick, white, silvery, or red patches of skin. It is thought that psoriasis occurs when the immune system overreacts, causing inflammation and flaking of skin. To confirm the diagnosis, you should get a biopsy skin done. This will rule out eczema or psoriasis and confirm the diagnosis.
