Doctor's answer:

Contact dermatitis can be treated with topical medications, and it is not necessary to rely solely on oral medications. Itching does not necessarily indicate improvement.
It is recommended to follow a light diet, avoid allergenic foods such as seafood, and use topical medications. For significant redness and swelling, you can apply calamine lotion or similar products. Small papular rashes can be treated with creams like Wifukang or Sanjiu Dermatitis Cream. If the condition does not improve, seek medical attention promptly. Focus on a light diet recently. Wait until the pregnancy test results are available before further treatment.
