can be a possibility
I have seen all the attached pics. Thanks for the same.
I could appreciate multiple erythematous scaly as well as excoriated raised lesions over the legs prominently over knees. Your fungal test is already being done, so that rules out the fungal etiology.
The other likely possibility is dermatitis
with secondary excoriations. It manifests in similar fashion.
For that, i usually advise my patients to apply a cream containing a combination of moderate potency steroid
and antibiotic like mupirocin
to be applied over the lesions twice daily.
For symptomatic relief, you may take tablet fexofenadine
in morning and levocetrizine in night time.
Additionally apply a good amount of moisturiser over whole body preferably after bath on semi wet body.
But if you strongly feel like having scabies, there is no harm in doing a topical course of antiscabiecidal therapy.
For that, you may apply permethrin cream/lotion 5 % once overnight application in addition to above mentioned treatment.
Disinfect your all the clothes used within past 3 days.
Don't worry. You may discuss my opinion with your doctor, i am sure he/she will agree with my opinion.
I hope it helps. If you have further query, you may ask me.
