my sister made the mistake of her life by using meth last weekend, it was from what she says for the whole weekend not just a day, she has a rash going from the left side of her neck to her armpit and a swollen gland only on the left side of her neck, its red from rubbing it, itchy, and small pimples without heads scattered, she has only itched not picked where they are, its been a whole week now and its not getting worse or better, what can be used to help them go away and is it contagious to someone like me who is around her but hasnt used?
Hi, Welcome to Chat Doctor, This red rashes and sometimes itchy over skin neck could be due to eczema or atomic dermatitis due to that method. More than any other field, in dermatology one needs to inspect with eyes what the skin condition is, how it looks, how is that redness or itching etched important thing is to diagnose first rather than treatment. You can go to skin specialist for detailed history of your sister and inspection of rashes to have a clear diagnosis. She might require topical corticosteroid like beclomethasone, clobetasol or mometasome with antihistamines orally to reduce itching. Some time oral antifungal once dosage with prednisolone are also effective. So, you must take her to the doctor. And yes, this is not contagious, so need not worry about it.
