Hello,
There can be many possibilities for these symptoms including granuloma annulare, lichenified eczema, scabies if they are bite like, lichen amyloidosis, pityriasis rosea and hypertrophic lichen planus. To confirm the diagnosis, you need to get an examination and preferably a biopsy done from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
discolor skin can be due to virtilego n is due to depigmentation of your skin........it dont have any relation with your anemia i guess....you should see a skin docter.take care
