I think I Have a Fungus on my nails
My nails are thin, thick or breaking
Thick Nails The main conditions are
Traumatic dystrophy with age - Minor recurrent traumas to the nail matrix eventually lead to a thickened misshapen nail. Vascular impairment also plays a part. Common in the elderly involving the little and big toes.
Psoriasis - Severe dystrophy in some cases. Associated with tendency to get psoriatic arthritis.
