Hello, Welcome and thanks for posting your query to Healthcare Magic. As per your query you had history of surgeries for kidney and have underarm odor. It is a common phenomenon in all the persons to have sweating all over body but specifically at underarms site due to presence of bacteria we get kind of body odor. Now it depends form person to person according to the sweat secreted and the maintenance of the hygiene. If the sweat is secreted in higher amount or the hygiene is not proper then it leads to the typical body odor. It also depends on the type of diet consumed. For the betterment kindly follow the suggestions below: -wear cotton clothes and cotton undergarments. - -change clothes two time a day. -Do simple cold compressions multiple time a day initially and then two time. stay away from heat and humidity. - do not consume food with garlic or onions or related food items. use antiperspirant powders at underarms. there is no correlatin of lymphoma in this condition so rest asured about this condition. Hope these information will help. With good health wishes Dr Sanjay Kumar Kanodia MD (Dermatology & STDs)
