Hello ic.brooks, Thanks for posting your query. I think your problem is not the infection but the intertrigo, it is a condition of moist raw itchy skin which becomes reddish and develops in areas that are in contact all the time, like in the armpits, the outer side of labia/scrotum and inner side of the thighs. Wearing synthetic under garments hampers the circulation of air and retains moist making the problem worse. You should avoid tight pants and synthetic under garments and keep the region dry most of the times. Immediately wipe and dry yourself with thick cotton towels after you take bath. You should use a medicated dusting powder containing Clotrimazole/miconazole/salicylic acid, thrice a day. The cannulation for angioplasty through local skin does not seem a probable cause. I hope this answers your query. In case you have any follow up queries or doubts, you can forward them for me, and I shall be glad to help you. Please accept my answer in case you do not have further queries. Wishing you good health
