Hi, I can understand your concern for the multiple of problems. In my opinion it appears to be allergic contact dermatitis rather than scabies. In this condition there are eruptions along with moderate itching and in more aggravated cases there is appearance of more redness. In this condition a thorough history of contact allergens are to be taken and accordingly a specific diagnostic technique known as patch test is to be undertaken. If I were your dermatologist then would have suggested you to apply medium to high potency steroid cream application such as fluticasone or mometasoen along with an antihistamine such as Loratadine twice daily. All the best.
