Explanation
Fingernail discoloration can happen for several reasons. One common cause is drug-induced nail disorders. Some medications can lead to changes in nail color, as noted in the medical literature.
Another possibility is blue nail discoloration, which might be linked to certain health conditions affecting blood flow or oxygen levels. This can make nails appear bluish.
Finally, fingernail clubbing and chromonychia (a term for nail color changes) can also occur due to various health issues. These changes might be associated with underlying diseases, and it's essential to consider these possibilities when evaluating nail discoloration.
If you notice any sudden or unusual changes in your nail color, it might be helpful to consult a healthcare professional for further evaluation.
