Hi,
Recurring rashes and fever blisters on the arms and face can be caused by a variety of factors. Some possible causes are:
* Allergic reactions: The rash could be a result of an allergic reaction to something he has come into contact with. This could be food, medication, or cosmetic product.
* Viral infections: The fever blister could be caused by a viral infection such as
herpes simplex virus. The rash could also be a result of a viral infection.
* Contact dermatitis: The rash could be a result of contact dermatitis. This is a type of
skin inflammation caused by contact with an irritant or allergen.
* Autoimmune disorders: Certain autoimmune disorders can cause rashes on the skin. These include lupus,
dermatomyositis, and
scleroderma.
* Stress: Stress can cause flare-ups of skin conditions such as eczema and
psoriasis.
To determine the underlying cause of the rash and fever blister, your boyfriend should consult with a healthcare provider. They may perform tests to diagnose the condition and recommend appropriate treatment options.
Take care. Hope I have answered your question. Let me know if I can assist you further.
