He: He may be dealing with a fungal infection aka jock itch (tinea cruris). An over the counter anti-fungal cream like Clotrimazole should help if this is in fact the problem. On the other hand, if the small red bump persists, or is very painful there may be something else going on like a genital wart, herpetic lesion, or bacterial infection (abscess). I suggest he try the Clotrimazole first, and if that does not work see a doctor.
Best of luck and happy new year. ...Read more

If after a tick bites you and there is a little red bump that itches sometimes, is that okay?

Usually OK: Foreign proteins from the tick's saliva can cause a mild allergic reaction, resulting in an itchy bump, a tick bite granuloma, that may take a month to flatten. This is not the rash of lyme disease, and is not a cause for worry. There are prescription creams that can flatten this bump faster. ...Read more

Dermograghism: See a dermatologist. Meanwhile you can take a daily antihistamine. The best one for this is Zyrtec. The generic, cetirizine, is just the same only cheaper. This is a physical urticaria, not allergy. When the skin is stroked, mast cells release histamine, causing itchy, elevated areas in the shape of the contact. Thus you can write messages on your skin. ...Read more
