<s>[INST] I self diagnosed my family for scabies after three visits to doctor over dry skin and possibly allergies. We used the Prometerin treatment two days ago. We are still itchy but I understand it will take two weeks to shed the bugs from our skin. My question is why are my thighs bruised. Am I itching that much at night and causing bruising? [/INST] hithis seems to be scabies with secondary bacterial infection , can be due to the itching or the lesions getting infected.application of 10% benzyl benzoate or permethrin is the treatment for scabiesit is better to meet your dermatologist, to add up with one course of anti-biotics to prevent the dermatitis or secondary infection.please do not meddle or scratch the  infected area.all the besttake care </s>
