Hi there...I can understand your concern. From the picture it looks like you could be suffering from prurigo nodularis, lichen planus, allergic contact dermatitis, eczema. Some skin conditions can persist for long duration. Don't lose hope so early. You will require regular followup. You can also get a skin biopsy done at any college associated medical hospital for less price and confirm the diagnosis once. So kindly followup with a dermatologist at the hospital.
