The erythema multiforme rash
The EM Rash can consist of dozens of target-shaped (bull’s-eye pattern) lesions that develop over a 24-hour period. These Lesions can start on the backs of hands and tops of feet before spreading to the trunk. They may also develop on the face and neck. The arms may be more affected than the legs. These Lesions can be concentrated on the elbows and knees.
Erythema multiforme minor
In minor cases of EM, there are Lesions covering the affected area. The Rash will affect both sides of the body. For example, if it’s on one leg, it will also affect the other leg.
If you have EM minor, you may have no symptoms other than feeling like the Rash is Itching or Burning and perhaps a low fever.
Erythema multiforme major
In cases of EM major, there can be additional symptoms, such as:
- joint ache
- a brownish color to the Rash once it fades
EM major lesions can also seriously affect any of the body’s mucous membranes, most often the lips and interior of the cheeks. It can also affect the:
- bottom of the mouth, palate, and gums
- genitals and anus
- trachea (breathing tube)
- digestive tract
Lesions in these areas may cause Swelling and Redness with blisters. The Blisters also break, leaving painful, large, irregularly shaped ulcers covered with a whitish membrane. When the lips are affected, they’re swollen and covered with a bleeding crust. There can be difficulty speaking and swallowing because of pain.
