Doctor's answer:

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