Dermatology Questions? Ask an Online Dermatologist.
HiCustomer Are you in good health otherwise? And is there any redness or rash along the hairline in back?
This is a comon place for inflammatory or autoimmune skin conditions such as seborrheic dermatitis, psoriasis and dyshidrotic eczema. Any of these can involve the hands as well. There tends to be dryness, lots of itch and flaking...due primarily to dysfunctional oil production in the skin. While it is always a good idea to see a dermatologist when one has a new rash, both to nail down the diagnosis and to get started on a rational treatment plan, all of these conditions are treated in a similar fashion...at least initially.
Principles of care include avoiding hot water and drying soaps or chemicals, frequent hydration and use of moisturizers, removal of scale when possible, and anti-inflammatory creams to reduce the underlying process.
These conditions often affect hair-bearing areas, including the axillae. Fungi also frequently inhabit this area as they like warm, moist, dark areas. Some rashes worsen with secondary infection by a dermatophyte (fungus). Either way, using an antifungal cream such as miconazole or clotrimazole twice daily can be helpfu. Some individuals need to alternate an anti-fungal cream with an anti-inflammatory cream to get their rash to fade.
Also consider any chemical agents that might be touching these areas such as a shampoo, conditioner, underarm deodorant, new soap or lotion. One must alwasy rule out an allergic reaction as the cause. This can also improve with anti-inflammatory creams (as well as avoidance of the allergen).
