<s>[INST] I had a small read rash on my neck before my uncle s wedding where I wore a heavy artificial necklace. The rash has worsened. It has become red, extremely itchy, stinging and clear pus comes out too. It has spread all around my neck and chin . I tried using betnovate , mederma , soframycin, boroline and cutisoft but these creams either worsened it ir had no effect. It has been 1.5 weeks now. I am on a vacation and there is no dermatologist around. What do I do? [/INST] gud morng.. the symptoms u have mentioned points towards contact allergic dermatitis occurring due to allergy ..hence u should even take oral anti histamine trablets to control ur allergy ..tablet levocetrine twice daily for 3days can be taken .as ur having pus too ,its a sign of secondary bacterial infection and so taking antibitic like erythro twice  for three days also will help u.. continue betnovate -g ointment and better take good diet full of iron rather avoiding some foods.. cause strengthening ur immunity will reduce the condition earlier ..or u can even take iron tablet daily one for atleast ten days.. dont do itching over the rash and avoid further ornaments in future too ..as ur allergic to it..usually such rash takes nearly 2wks to get relieved completely so have patience and take the treatment .. </s>
