त्वचा में खुजली

Persistent skin itching can indeed be frustrating, particularly when it interferes with sleep and daily activities. Since your allergy tests came back normal, it’s a good idea to explore other potential causes. Chronic pruritus (itching) can sometimes be due to dermatological conditions such as eczema, psoriasis, or dermatitis. Fungal infections like athlete’s foot can cause itching too, especially if it spreads. If your symptoms began after hiking, consider whether you might have encountered an irritant like poison ivy or oak, which can cause a rash that lasts for weeks. It’s also important to think about factors like stress or even systemic conditions that can sometimes manifest as skin itching, such as thyroid disorders or liver issues. Given you’ve tried hydrocortisone without relief, over-the-counter antihistamines might offer some temporary help, particularly if there’s an allergic component. Maintaining good skin hydration with moisturizing lotions that are fragrance-free can also reduce irritation. Avoid hot showers, as these can exacerbate itching. Given the duration and intensity of your symptoms, and failure to respond to initial measures, it might be time for a follow-up appointment with a dermatologist. They can provide a more thorough examination and might suggest targeted treatments or skin biopsies if they find clinical clues pointing toward specific dermatoses. If you experience any new concerning symptoms such as jaundice, significant weight loss, or abnormal blood tests, please seek a more urgent assessment to rule out systemic causes.
