Most rashes improve on their own or with over-the-counter treatment; however, if symptoms persist or worsen, consult a doctor, states MedicineNet. If there are any symptoms of joint pain, fever, head or neck pain, swelling or evidence of a tick bite, seek medical attention, recommends Healthline.
A rash is a skin inflammation that produces red bumps, skin discoloration and itching, reports MedicineNet. The appearance of different rashes may look similar, but bump formations vary and may be accompanied by blisters or scaling. The most common types of rashes include hives, poison ivy, eczema, psoriasis and heat rash.
Rashes can be caused by various types of bacterial, fungal, viral or parasitic infections, and from illness or fever, explains MedicineNet. Many rashes are brought on by an underlying medical condition. Anti-itch creams, antifungal medications, oral antihistamines and moisturizing lotions are some common nonprescription remedies available.
Rashes can also be caused by a sensitivity, allergic reaction or side effect of medications, according to Healthline. Contact dermatitis is a common rash caused by various soaps, dyes, chemicals or poisonous plants. Home treatment using gentle cleansers and warm water may be effective for many topical rashes. It is also important to resist the urge to scratch, which may cause the rash to spread and prevent healing. One percent hydrocortisone cream can be effective to relieve painful itching.
