What is the treatment for itching without rashes on my upper body parts?

Hi,

Welcome to icliniq.com.

I understand your concern. As per the history provided, it is cholinergic urticaria. The presence of excessive itching with temporary red itchy hives or rashes appearing following a bath or changes in temperature is urticaria. It may stay for minutes to hours and then subside. For some individuals, the rashes may appear after stress, working out, following climate changes, and sun exposure. It is a hypersensitivity reaction meaning your body is more sensitive than usual to temperature changes following sun exposure, and may also cause reactions to insect bites. There is nothing to worry about as there are medications for the same. The medications can be taken for a month and then may be stopped. But since it may also appear with temperature changes later in life, the same medication may be used. For some, it may eventually stop occurring in the future. But others may experience the same on and off again. It is not contagious and will always reduce in a few hours. I would suggest the following. Take Tablet Fexofenadine 120 mg and Montelukast 10 mg once daily after dinner for one month. Hydrocortisone 1 percent cream may also be used on the red rashes when they appear. However, it is a strong medication and should be used only in the smallest quantity possible in a very thin layer only once daily for a maximum period of ten days if used on consecutive days. If they are used only when rashes appear, you may do so with a minimum gap of three days between each application. Their usage is not mandatory, as the rashes may subside within a few hours. However, this medication would be helpful in case of reducing excessive itching. Ensure staying indoors at room temperature during rains, bathing with normal tap water, etc., would be helpful. Applying aloe vera gels may be done to soothe the area. Avoid stress as much as possible, and protect yourself in case of sun exposure by using physical protectants like caps, goggles, long sleeve shirts, etc. Avoid spicy and hot food, red meat, and fried food to prevent sudden changes in body temperature. Consume more fruits and vegetables and follow a healthy diet as much as possible. Consume 12 glasses of water daily to maintain your body temperature and hydration. This medication can be used later when symptoms arise as well. Since it is the body's internal response to allergens, they may appear on and off in case of changes in body temperature. However, it is also advised to note any specific allergen while consuming particular food items and avoid them. The main factor to consider to prevent their appearance is to avoid the allergen. I hope this helps. Thank you.
