C) Warning signs and symptoms of a dangerous skin rash

As you can see, there are mild and very severe causes of skin rash in adults. Thus, it is important to be aware of a few warning signs and symptoms of a dangerous skin rash in order to identify them early and talk to your doctor to receive treatment as soon as possible.
The most important warning signs are as follows:
- A skin rash that is very extensive: In infectious diseases, the skin rash can cover the majority of the skin. In children, chickenpox and other infectious diseases are not dangerous but should be attended by doctors in the case of adults.
- A skin rash that spreads rapidly: When the skin rash spreads in a few minutes or one or two hours, it may be caused by a severe allergic reaction, and needs to be addressed properly.
- A skin rash with signs of infection: If you started scratching and the skin rash is oozing with signs of infection, you might need to ask your doctor and get antibacterial creams to control the infection.
- Spontaneous bruises and bleeding: One of the most concerning types of skin rash in adults are those associated with spontaneous bruises, especially if you experience bleeding in your gums, blood in the stool, and other hemorrhagic manifestations.
- Skin rash associated with breathing problems: If you experience redness in your skin, itchy skin, and breathing problems, it may be caused by a food allergy. Do not hesitate and talk to your doctor to receive appropriate treatment.
- Skin rash associated with fever: If you have skin rash and fever, it is probably an infectious cause. Infectious causes of a rash in adults are sometimes dangerous. Another possibility is leukemia, so make sure you talk to your doctor as soon as possible.
