Hello,
It can be due to cholinergic urticaria or dyshidrosis. It is a form of chronic hives that is caused by an increase in body temperature but can be idiopathic also. Take some antihistaminic like Benadryl or Claritin and apply some calamine lotion on the hives. If the symptoms persist then please get it examined from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Skin rashes, spots or dryness are all very common symptoms of anxiety and stress. It is quite common to get an eczema like rash around the nose, cheeks and forehead. They are nothing to worry about and usually disappear when you start to feel better. i usually get them on my arms !!
