I was just looking up beaus lines, since i have lines all up my right thumb nail. the left isn't so bad, just one dent, that gets worse then gets better. it'll range from a small lump to a bigger one. my right nail has gotten worse over the years. itll range from line to a few and/or a horrible lump. ive filed it down and it tends to help. (im not sure if thats wrong) Ive gotten them both from when i was little and smashed my thumbs on a metal gate. I read beaus nails go away after a while but its been a very long while and still no luck. is it possible i may have something else?
Do your ridges run from side to side? If so, that qualifies them as Beaus lines.
Beau's lines can be seen in the fingernails, thumbs, toenails, or all nails and may be confused with nail ridging. This phenomenon was originally described in 1846 by the French physician Joseph Honoré Simon Beau. These lines are caused by diseases that affect the entire body, including malnutrition, heart attack (myocardial infarction), liver diseases, severe infections (such as mumps, measles, pneumonia, and others), and metabolic disturbances, including poorly controlled diabetes. However, Beau's lines can result from any disease process or illness that is severe enough to affect the growth plate of the nail. Some other reasons for these lines include trauma, hypocalcaemia (low calcium), as well as drugs used in chemotherapy and skin disease. Beau's lines can also be seen one to two months after the onset of fever in children with Kawasaki disease. Sources: wikipedia and medicinenet dot com
You know you've had a traumatic injury to your nails and possibly you have another of the causes mentioned here. If you want to trim your nails, go ahead, they're your nails, make them appear the nicest you can. Neither source gives a time limit to Beaus lines.
