It sounds like spoon shaped nails which is due to koilonychia. Koilonychia is usuall
y caused by iron deficiency anemia.These nails show raised ridges and are thin and concave.I would suggest that you get your Hb levels estimated and also take some iron supplements for some days.If the symptoms persist then pls consult a dermatologist.
Hope it helps. Take care and pls do keep me posted on how you are doing or if you have any additional queries.Kind regards.
