Welcome to ATD,Thank you for the query.
The following skin conditions may be the cause for itchy marks on your foot:
dermatitis inflammation of the skin
dermatographism-caused by pressure on the skin.
irritant substance that might have come in contact.
Whatever may be the exact cause,but the lesions are now healing,just do not worry,take tab cetirizine 10 mg at night one daily to relieve itching, apply a good amount of moisturizer,avoid scratching it,do not apply soaps and detergents and take a cool bath.
Do consult a dermatologist for proper evaluation and management.
Hope this helps. All the best.
