I've been noticing this white powder under my nails whenever I scrape my scalp. It's not itchy, and I don't see flakes or dandruff. I shower daily, so I'm quite clean. The powder is a bit waxy. Is this just sebum, or could it be something unusual? Is this normal for scalp skin and only becomes visible after scraping?

The white powder you are noticing when you scrape your scalp is likely sebum mixed with dead skin cells. Sebum is an oily substance produced by the sebaceous glands in the skin, including the scalp. It is normal for sebum to be present on the scalp to help keep the skin and hair moisturized. When sebum mixes with dead skin cells and other debris, it can form a slightly waxy substance that becomes visible when you scrape your scalp. This is a normal occurrence and is not necessarily abnormal. However, if you notice any changes in the color, texture, or odor of the white powder, or if you experience any other symptoms such as itching, redness, or inflammation, it is advisable to consult a healthcare professional for further evaluation and advice."

I've got this heat bump on my left buttock that's been around for about six days now. It's getting bigger and it's really painful. Also, I've been having a fever. Could you suggest any creams or medication for it? And are there certain foods I should avoid? Should I stick with regular soap for cleaning it, or is there a special soap I should be using instead?

Surgeon opinion is advised to the patient.
