Your symptoms could be due to a condition called dermatographia (skin writing), in which the skin reacts strongly to light pressure or touch, causing swelling and redness. Allergies, certain medications, or underlying medical conditions may also contribute. Avoid scratching or rubbing your skin, use gentle, fragrance-free moisturisers, and take antihistamines (such as cetirizine or loratadine) if advised by a doctor. It is important to see a dermatologist to confirm the cause and receive appropriate treatment.

Yes, frequent exposure to diesel can be the cause, as it strips away the natural oils from your skin, leading to dryness, wrinkles, and skin damage over time. The most important step is to avoid direct contact by wearing protective gloves at work. Use a thick moisturising cream or emollient several times a day, especially after washing and at night. If your skin becomes very red, itchy, or cracked, please consult a doctor for further treatment.

Persistent vomiting and not being able to eat for five months can lead to a serious imbalance of salts and fluids in the body, which may be causing your tiredness and leg cramps. It is very important that you see a doctor as soon as possible for blood tests, including kidney function and nutrient levels, to find the underlying cause. Until then, try to take small sips of water or oral rehydration drinks to prevent dehydration.
