A rash on both forearms is very common and usually highly treatable. For itching and mild inflammation, you can apply generic hydrocortisone 1% cream twice daily. If an allergic reaction is suspected, an oral antihistamine like cetirizine or loratadine can provide daytime relief, while diphenhydramine can help if itching keeps you awake at night. Applying a gentle, unscented moisturizer containing colloidal oatmeal will also help soothe the skin barrier. Try to avoid scratching to prevent irritation. If the rash worsens, spreads quickly, or is accompanied by a fever, please see a doctor for a professional evaluation.

Pain after sex for both partners is commonly caused by friction, inadequate lubrication, or a shared infection like yeast. For immediate relief, gently wash with warm water and apply a plain, unscented moisturizer or over-the-counter 1% hydrocortisone cream externally to soothe irritation. If a yeast infection is suspected, an antifungal cream like Clotrimazole can be applied. Avoid sexual activity until the pain resolves. Because both of you are experiencing symptoms, please consult a doctor to rule out sexually transmitted infections or allergies to latex/spermicides. Using a water-based lubricant during future intercourse can significantly reduce friction-related pain.

Pityriasis rosea is a common skin condition that usually starts with one larger patch followed by smaller pink or reddish rashes on the body. It is not usually dangerous and often improves on its own within a few weeks to a couple of months. The exact cause is not always clear, but it may be linked to a mild viral reaction in some people. The rash can become more noticeable with sweating, hot showers, or tight clothing, and some people may also feel itching. Using mild soap, avoiding harsh skin products, and wearing loose cotton clothes may help reduce irritation. Try to keep the skin moisturised and avoid scratching, as this can worsen discomfort. If the itching is troubling, a doctor may suggest creams or medicines for relief. You should see a dermatologist if the rash spreads rapidly, becomes painful, affects the face or mouth, or does not improve after several weeks.

Clean the bite gently with soap and water, apply an antiseptic, and keep it covered. Take a painkiller if needed and watch for redness, swelling, or pus. Inform a doctor if it worsens or if signs of infection appear.

Your itchy patches suggest an allergic reaction or contact dermatitis, likely triggered by histamine-rich foods like brinjal and certain fish. Because diabetes can impair skin healing and increase infection risk, careful management is essential. First, strictly avoid these trigger foods. For temporary relief, you can apply a mild, over-the-counter 1% hydrocortisone cream twice daily for up to a week, combined with a thick, fragrance-free moisturizing emollient to protect your skin barrier. An oral antihistamine like cetirizine can also help calm the itching. Please consult a dermatologist or your doctor for a formal diagnosis and a safe, tailored treatment plan.

Vulvar itching can result from multiple causes, such as irritation, allergic reactions, fungal infections, dryness, or skin conditions like dermatitis, and the appropriate treatment depends on identifying the exact cause. Hydrocortisone 1% is a mild steroid that may reduce inflammation and itching, but it should not be used on the vulvar area without a proper medical evaluation, especially if the cause is unclear. Using it without diagnosis may mask an infection or delay correct treatment. It is important to consult a gynaecologist or dermatologist for proper examination and appropriate treatment based on the underlying cause.
