What vitamin deficiency causes vertical lines in fingernails?

Doctor 1

Answered by 1 Apollo Doctors

Our nails naturally develop slight vertical ridges as we age. However, severe and raised ridges can be a sign of iron deficiency anemia. Nutritional deficiencies, such as a lack of vitamin A, vitamin B, vitamin B12 or keratin can result in fingernail ridges. Hormonal changes can also cause ridges to appear.

I've been using erythego gel for my Rosacea for about a year and a half without issues since it was prescribed by my doctor. But lately, I've developed contact dermatitis, and now every time I apply the gel, it seems to make things worse. Could the gel be causing my contact dermatitis?

Erythego gel contains erythromycin, which is an antibiotic commonly used to treat acne and rosacea. However, some individuals may develop an allergic reaction to erythromycin, leading to contact dermatitis. I recommend stopping the use of erythego gel and consulting with your doctor for an alternative treatment option for your rosacea.

I've noticed some small, painless bumps on the foreskin of my penis that don't itch or bother me at all. They've been there for over a year now, and Im just wondering what these might be. I've attached a photo for reference. Could you let me know what these bumps are?

May be Fordyce spots. Fordyce spots are harmless, small, yellow-white or skin-colored spots that can appear on the shaft of the penis, the labia, or the vermilion border of the lips. They are a type of ectopic sebaceous gland and are considered a normal variation. There is no specific treatment necessary for Fordyce spots, as they are benign and do not cause any symptoms. However, if you are concerned about the appearance or if they are causing you distress, you may consider consulting a dermatologist.
