The boils on your legs are likely a bacterial skin infection. Because your current steroid lotion (betamethasone) suppresses the local immune response, it can worsen infections, so you should stop applying it on or near these boils. You may continue using the soothing calamine lotion on other irritated, non-infected skin. To treat the boils, apply warm compresses for 10 to 15 minutes daily to help them drain naturally, and do not squeeze them. You can apply a topical antibiotic ointment like mupirocin. However, since you have multiple boils, please consult a doctor promptly, as you may require oral prescription antibiotics to safely clear the infection.
