### input:
I woke up yesterday morning with red dots all over my thighs, they were flat, didnt itch , and everyone of them had a white ring around them. Throughout the day i noticed they were slowing spreading down my legs, some of them looked to have become swollen, some began to become raised and others stayed the same. Last night a couple of them began to itch but not all of them. I woke up this morning with more red spots, more that had become larger and swollen as well as more that started to itch. They have now made it down to my feet . It seems as if they are spreading possibly to my arms. I have about a handful on my arms. Other than the white ring around them they look very similar to a mosquito bite just without the annoying itch all day long. Do you have any idea what these may be?? I showed the doctors i work for today and they had no idea.

Hi, Welcome to Chat Doctor. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.  Based on the symptoms it appears to be contact dermatitis. Treatment includes washing with lots of water to remove any traces of the irritant that may remain on the skin. You should avoid further exposure to known irritants or allergens. In some cases, the best treatment is to do nothing to the area. Emollients or moisturizers help keep the skin moist, and also help skin repair itself. They protect the skin from becoming inflamed again. They are a key part of preventing and treating contact dermatitis. Corticosteroid skin creams or ointments may reduce inflammation. Carefully follow the instructions when using these creams. Overuse, even of low-strength over-the-counter products, may cause a skin condition. I advise you to follow the conservative approach as mentioned and if symptom persists i advice you to see dermatologist for exact diagnosis.  Hope I have provided the information you needed. Wish you good health. Take care.
