Hello Thanks for posting your query. I can understand your concern for the itchy red spots on the arms and legs. However the diagnosis of scabies cannot be made on this only. Moreover your girlfriend is not having any such symptoms when scabies is a highly contagious disease. The disease may be transmitted from objects but is most often transmitted by direct skin-to-skin contact with a higher risk with prolonged contact. It occurs in the area of the hands feet wrists elbows back buttocks and external genitals and intense itching at night is a common symptom. Diagnosis of scabies is made by scraping the skin and viewing the material under a microscope to see the characteristic mite or eggs. So you should get the investigation done to confirm the diagnosis of scabies and then only take the treatment. Permethrin and oral ivermectin are the best treatment options of scabies. Sometimes itching of scabies persists for a few days after completion of treatment also and sometimes there may be recurrent and chronic cases which may require oral treatment of ivermectin. There is a rule that all family members of the patient of scabies also need to be treated even if they do not have any itching or rashes. Hence please ensure that all your family members also get the topical treatment if the diagnosis of scabies is confirmed. Other than that atopic dermatitis and eczema can also present with symptoms like these. In such cases oral antihistaminics and topical application of calamine and steroids is very useful. Hence my suggestion would be to get investigated for scabies and if needed get a biopsy of the effected skin scrapings done to confirm the diagnosis. Permethrin does not cause itchy skin after its topical application but may cause slight skin irritation and rashes of scabies do not usually spread when the topical treatment of permethrin has been initiated. Hope that this information helps and hope that you get better soon. Wishing you good health. 喵小姐 15:58:51 Hello Thanks for posting your query. I can understand your concern for the single painless ulcer on the penis. You have not mentioned anything regarding your sexual history and the STD blood tests that you have got done but for such a painless ulcerative solitary lesion on the penis syphilis and lymphogranuloma venereum are two possibilities which should be ruled out if you are sexually active. People with primary syphilis will develop one or more sores. The sores resemble large round bug bites and are often hard and painless. Although single dose of penicillin is sufficient to treat the sore but some resistant cases may need repeated doses. You have mentioned that many blood tests for STD’s have been done but confirmation is required with a treponemal test such as treponemal pallidum particle agglutination (TPHA) or fluorescent treponemal antibody absorption test (FTA-Abs). If these have not been done then you should get them done. Lymphogranuloma venereum also presents as painless genital ulcer that occurs at the contact site. To confirm the diagnosis real time PCR can be done. Please check your lab investigations and if these tests have not been done before then you can discuss about these tests with your dermatologist and get them done. Other than that since there was no response to the antibiotic you should get the ulcer cultured for fungal infection and viral infection (due to herpes although less likely)also. It is less likely to be related to stress and it is important to rule out infection as the source of this ulcer. Hope that this information helps and hope that you get better soon. Wishing you good health.
