Why am I having rashes all over the body?

Hi,

Welcome to icliniq.com.

I have gone through your case. It is an allergic reaction to the temperature and lights used in the sauna (attachment removed to protect patient identity). Please use Calamine lotion. Apply twice daily for seven days. Also, apply 1 % Hydrocortisone cream on as many lesions as you can at night. Only take a small amount. You can continue with Benadryl pills or use tablet Cetirizine 10 mg at night for seven days. Please avoid driving after Cetirizine as this induces sleep. Do not use any Dettol or safeguard or any other antiseptics. Try using mild soap. Wear only cotton shirts. One can get prescription seasonal allergy medicine online by consulting a dermatologist through a telemedicine platform.

Hi,

Welcome back to icliniq.com.

Actually in your case, both heat and light are equally to be blamed for the rash. There are many types of urticaria, for example, heat urticaria or solar urticaria or cold urticaria and even aquagenic urticaria. And most often, we asked patients to ask themselves if they have been exposed to any precipitating factors like some food and drugs also causes them.

In your case, your history was quite clear about precipitating factors. However, almost 50 % of patients may remain unaware of their cause as they are doing too many things together. The best treatment of your case is the above treatment which I have prescribed you and to avoid the sauna at least for three weeks or until the rash recovers. Then my advice to you is to gradually increase exposure time and find yourself how much time you can spend there comfortably, like take 10 minutes initially, find out your tolerance point, and then always take the sauna for this time duration only. Otherwise, you may have a reaction. This is the most acceptable way of determining the acceptable point which we do in many allergies. It is slightly different from a typical heat rash.
