Excessive sweating and the resulting odour are very common and highly treatable. For your palms and feet, the first line of treatment is a topical antiperspirant containing aluminium chloride hexahydrate, applied to completely dry skin at bedtime. To address the odour caused by bacteria breaking down sweat, you can apply an antifungal or antibacterial powder containing miconazole or clotrimazole during the day. Washing daily with an antibacterial soap and ensuring your skin is thoroughly dry will also help. If these measures do not provide enough relief, a doctor can prescribe topical antibiotics like clindamycin. Rest assured, this is a very manageable condition.
