Did you at the outset visit a dermatologist
or is this all home diagnosed & treated? If not, your first objective is to go meet a dermatologist in your area.
Known exposure to scabies
et al is all good & must be treated but the incubation period
Firstly now, address the redness
of face & swelling et al which can be a reaction to either your tea tree oil application or the permethrin appln if you used it on the face. Take an oral antihistamine fexofenadine
180mg once/day & or a topical steroid
furoate) for the face twice/day for 2-3 days. This should settle the acute irritation.
Then, you need to reasess the scabies factor. Vist a dermatologist. There are various treatments available & DIFFERENT ways of applying each with precautions & cautions & best explained by your dermatologist. Scabies responds well to treatment & you should be rid of the itch in 24-48 hrs but sometimes the 'bite lesions' may take longer a week or so & may require application of topical crotamiton
cream. Also remember 'fomites' need to be treated.
Cheers & wish you good health & an itch-free skin.
