Darkening of Knuckles? It Could Be Vitamin B12 Deficiency
Just For Hearts1 min read
Are you noticing darkening around your knuckles? This could be a sign of Vitamin B12 deficiency.
In cases of B12 deficiency, there is an increased accumulation of melanin in the skin, especially near the joints, which causes the darkening.
If your MCV (Mean Corpuscular Volume) is above 100 and you observe darkening on your knuckles, you can suspect Vitamin B12 deficiency without needing expensive tests.
Even without costly investigations, just by observing this symptom, one can make a clinical diagnosis.
